Fool-proof Migrations from Joomla 3 to Joomla 4.x

This Joomla! extension simplifies your migration process - ensuring no downtime, crashes, or "white screen of death."

With just one click, MigrateMe 4 will check your current Joomla 3.x system, apply updates, repair database issues, and create a standalone environment to safely test the new Joomla 4.

Enjoy all the latest features and seamless integration with third-party extensions, custom templates, and plugins.

Migrate your old data, files, and access with ease and start using Joomla 4 today!

How to migrate your Joomla 3.x system to Joomla 4.x

 

Upgrade to Joomla 4 with confidence using MigrateMe 4.

This extension will create an exact version of your Joomla 3.x site ... but with a Joomla 4.x core, in a separate development environment.

This means you can test the new Joomla 4 system, confirm it *actually* works well, and check how nicely (or not) it plays with your third party extensions, custom template, plugins and so forth.

It's a one-click solution that will:

  • Check your existing system, and ensure you're at a good starting point (must be Joomla 3.x or later)
  • Apply any missing J3 updates, to ensure your database structure and filesystem are fully up to date
  • Optimise and repair any database issues
  • Create a standalone development environment - so you can safely test the new system
  • Migrate your old data, files, folders, third party extension data
  • Flawlessly set up your new J4 system with the correct users and access
  • Create a 'safe mode' Joomla 4 environment: you can upgrade even if your extensions are not J4 compatible
  • Avoid the "white screen of death" common with J4 updates
  • Allow you to safely apply any third party updates without any risk to your live system
  • Back up your old system so you can roll back if needed
  • Leave your live site untouched and running until you're ready to deploy J4

Comes with a full, money back Joomla 4 upgrade guarantee!

All purchases come with a migration guarantee. So if you install MigrateMe 4 and it doesn't migrate your system - or hits an error that you can't get past - get in touch, and our incredible support team is here to help!


What this solution *won't* do:

MigrateMe 4 is great, but it can't update your third party extensions for you. After migration, you'll need to download the latest Joomla 4 version for each extension from the Joomla Extensions Database, and install on the new J4 environment.

MigrateMe 4 also can't automatically update any third party templates, or custom code - you'll need to update, or ask your developer / distributor for the latest Joomla 4 versions

Why buy Migrate Me 4

Migrate Me 4 is more than just software. It's a guarantee that your system will migrate succesfully to Joomla 4.x. Migrate Me 4 is far more powerful and intuitive than any other method of upgrading - it eradicates any risk of migration not working, or the upgrade introducing problems to your system.

And for your complete peace of mind, purchase entitles you to full support - just let us know if you need anything, and you'll experience the award-winning, customer-first assistance that we're known for!

Hi Patrick,

I am glad you are enjoying the ease of MigrateMe 4. If you would leave a review for us on the Joomla Extension Directory that would be great! https://extensions.joomla.org/extension/migrateme-4/

To answer your questions, MM4 makes a copy of your database tables, giving them a prefix named mm4_. It only ever makes one copy.

If you have completed your migration, did you remove the /MM4 files and tables? If not, this video will show you how to do that. - https://cybersalt.com/migrateme-4/how-to-remove-your-joomla-4-test-migration-area-and-uninstall-migrateme-4

If that is not the issue, and since your host said they don't know much about Joomla, I would be happy to log into your hosting and take a look. If you want me to do that, contact me through [email protected] and we'll get that going.

God bless,

Made MM4 site copy a week ago. despite being asked not to, client input two dozen new articles with images. If i now preass the push to live button... will content put in AFTER the mm4 copy is made be preserved? Or does the push overwrite the entire content table. What about images added in after first mm4 creation? do they stay put?

Hi Tim ( apologies, I had already emailed you when I realised that this was the correct forum for any questions)

I’ve run the upgrade exactly as suggested – safe mode etc. – and, after a few glitches, the staged site opens as expected. However, the menu urls don’t load – I get a 404 ERROR. – i.e. the old urls are fine -e.g. https://www.sourcewellbeingcentre.co.uk/meet-the-team - but none of the new ones do - https://www.sourcewellbeingcentre.co.uk/mm4/meet-the-team
Are the URL’s supposed to work even with the appended MM, or will it simply work when I finally press the GO Live button and the “mm” disappears ?

my experience with this... i have admin tools pro installed in nearly every site i've run MM4 on. the issue is the htaccess file. using FTP, go to the mm4 directory. rename the .htaccess file something like WAShtaccess. Delete the htaccess.txt file that's in the mm4 directory. Download a new full Joomla 4.3.4 zip file. Unzip it. Upload that folder's htaccess.txt file. Change it to .htaccess

that will get rid of the 404 menu errors.

I had about 30 Joomla 3 web sites to migrate to 4. I started manually doing this. Take a backup of the original site. Install it in a sub domain and then run the Joomla 4 update. Install new components, modules plugins for 4. Test and test again. Almost there and then the site crashes. Start all over again.
Then came migrateMe4 and what a dream it was to migrate all my remaining sites. It has saved me a shed load of time, not too mention lower blood pressure! I can highly recommend it. Knowing there is Tim in support is an added bonus although I have only had to contact him once. An excellent component well worth the money.

I used MigrateMe4 to upgrade two Joomla 3x sites.
Tim helped out when I had a few technical issues.
Actually he helped A LOT (thanks Tim ?)
I recommend this plugin very highly. It makes the upgrade from J3 to J4 so easy.
I remember trying the Joomla update tool built into J3 and wondering how I would ever make it happen.
Having the mm4 staging area, which enables you to trouble shoot (until everything works) is so helpful.

Do yourself a favour and grab this plugin. You won’t regret it.

Many thanks,

Hi Carlos,

Tim Davis here, helping with support.

MigrateMe4 creates a staging area where you ca easily test your J3 to J4 migration as many times as you need, without breaking your live site, or requiring you to manually make test areas again and again.

The actual migration that takes place is not affected by MM4.

Unfortunately, there is no version of K2 that works with Joomla 4, and so you will not be able to migrate to Joomla 4 until one is out or if you move you K2 content back into the core Joomla articles component.

I have experience with moving K2 back into the Joomla core. You are welcome to email me and we can discuss how you can do that.

Hi Chris,

If you add this to the your site url (after you have logged into the back end) the MM4 log may give you a clue as to what happened during the process of duplicating the tables of your live site:

/administrator/components/com_migrateme4/log.txt

MM4 would not do anything differently with CE than anything else. That said, all MM4 does is create the testing area for your migration so if something untoward is happening with an extension and/or its tables it is probably something that would have happened during the migration process without MM4 as well. I have seen migrations where core tables where not copying or creating properly. In fact, it happens to some core tables more often than others regardless of the migration process.

Keep me posted!

Hi Ludvig,

Sorry for the slow reply, I am travelling this week on vacation.

Regarding your migration plans, there is no J2store version available for use on live J4 sites, so I recommend you wait before doing your migariton.

Regarding support, we fully support MigrateMe 4 while you have an active subscription. MM4 creates a test area for you to do your migration work. We often help with some questions related to the initial steps of migration, but for more numerous or complex help with your migration(s) we can quote on that as well.

You are very welcome to email [email protected] about that or any other questions you have.

Is there a changelog area to show what the latest updates are for MM4?

I have noted that on earlier releases (pre _9778) that when migrating, certain extensions are actually disabled by the MM4 tool. Once the process is complete, I have to go re-enable them. One example is JCE Editor has a plugin that is disabled).

Hi Chris,

Sorry for the slow reply, I was away at a conference and forgot to check for comments!

MM4 has "safe mode" on by default, which disables non-core extensions in order to cut down on surprise breaks if something that isn't J4 compatible gets missed when you do a test migration. You can turn that off in the MM4 settings.

Here is the changelog since the beginning of the year:

Hi Tenenbaum!

MM4 will migrate the J3 only template, but that template will still break Joomla 4 - or at least not work with it.

MigrateMe 4 creates a staging are to test a migration from J3 to J4. The migration that happens is identical to what would happen if you ran the migration process on your live site. MM4 would not convert your template to be J4 friendly

Now about your template. If it is not J4 compatible there are a few ways to proceed before you do your migration.

My favourite one is to update the J3 site with a J3/J4 friendly template and then do the migration (as one needs to do with other none J4 extensions.)

However, if your site is fairly static, you could run the migration with MM4 and then get your site all done in J4 (including setting up a new template) and once you are happy with the results, one-click push your J4 site to live.

Back to your J3 template, if you really like the look of your J3 template you can make a template that looks just like it using an extension call Template Creator CK. If you want to now more about that, or have more questions, please email me - [email protected]

I hope that helps!

There is no mention of menus, modules and plugins. Do these reliably migrate? I have a fairly large site and i have a feeling that i will spend the money and this wont work. Maybe manually migrating will be faster...you know copy and paste or rebuild each module.

The page does actually mention extensions, templates, and plugins.

MM4 creates a staging area to test your J4 migration in. Once your J4 site is as you want it in that staging area you can then click a button and it will be pushed to replace your live J3 site.

The migration process remains the same in that staging area, so menus, modules, plugins, extensions, and templates are migrated - but as is the case with any method you have to make sure those things are J4 compatible and you should test on a copy of your live site. MM4 is by far the easiest way to create that testing environment.

Hi Barnaby
The first migration went very easily. Now when I went live on an Apache server for the second migration, neither the old nor the new site worked. Only with effort we could restore the initial state. Is there now a way to go live manually? We have not been able to do it ourselves. We would not like to keep /mm4 as a permanent addition in the address line when we assign the domain to this directory. Please help!

Hi David,

Each time you run MM4 inside of your Joomla site, the /mm4 staging area is completely replaced as if it was the first time you ran MM4.

So if run /MM4 and then see in the staging area some things that you don't want/need in your J4 site, I would go back to the J3 site, remove those things and then run MM4 again. In this way you will keep stepping toward having a J4 site that will be the one you are happy pushing to live.

That said, if you had made a whole bunch of changes to the J4 migration in the /MM4 staging area before you found something you wanted to remove, you could still try removing it right there. A lot of things do remove just fine, but I have found some things that were "fiddly" and since the goal is to have as clean a J4 install as possible when you push it to live, I would do as much removing as possible in J3.

Thank you for creating such a straight forward way to upgrade from 3 to 4! Everything worked great, even to the point of reverting to joomla 3 to make a minor change before rerunning for joomla 4. I did my homework first, getting everything ready and it worked! I'm a novice and was dreading how to do this without paying a fortune. Thank you Barnaby! and Thank You Tim Davis for your Youtube prompt to get me here! Best wishes to all.

When I set debug to "0" the backend doesn't work again. Seems it HAS to be set to "1"

Sorry for the delay in replying - the holidays and the flu have had me tending to support requests slower than normal.

If the site only works with debug set to "1" or "true" that means there is still something not working in J4 or the PHP version you have set. But I will admit it is very strange that is happening where the page does not work with both settings!

The installation folder is not deleted.
Would be REAL nice if we could delete the mm4 folder and DB entries and start over.
There is no example.htaccess in administrator/components/com_migrateme4
I cant log in to mm4 backend. Clicking log-in button does nothing.

This has actually happened to me a couple of times recently - there is a final stage of J4 installing additional languages and if that does not complete the installation folder does not get removed. We'll try to find out what causes this quirky occurence on some installs! Thanks for reporting it!

My default login points to the install directory.
https://myupdrade-j3/mm4/installation/index.php
even when I change it to https://myupdrade-j3/mm4/administrator/index.php

Is it better to simply disable Admin-Tools before migrate?
Id have to install their J4 version(s) anyway, which has different mappings.

I've seen this too and discovered it was actually my browser caching the target of that redirect - a pain indeed! I don't use Admin-Tools, so disabling that will not fix this. Trying to go to the admin login using an incognito browser tab or even clearing that install url from the browser cache is a possible work around for this.

Hi Tor,

Congrats on a successful migration from Joomla 3 to 4. I am so glad our extension helped.

Yes, you can remove the MM4 folder. In fact, if you go into the MM4 extension you will find a button which will remove that folder and the MM4 tables that were created in your database for the initial J4 testing you did. After that you can uninstall the MM4 extension from your site and you'll be free as a bird in the J4 world!

BTW, if you have already removed the MM4 extension and can't access the one click button, just remove the tables that begin with the prefix "mm4_" in your site's database - and the "mm4" folder in your file space (as you have already discovered.)

Remember to make a full backup of your site when doing the above.

God bless

Tim

If I am currently using StageIt, should I remove the staging environment and plugin before running MM4?

Hi Mike,

Yes, I would remove the staging environment before running MM4. That will cut down on the files being copied during the migration and once successfully migrate to J4 and push that live, you'll have an unnecessary J3 copy of your site files without any DB tables.

And of course, make a backup of your J3 site and keep it in a safe place outside of the folder your Joomla site is in!

Hello Ashish,

MM4 makes a copy of every table in your Joomla 3 install, so yes, your Virtuemart and Membership Pro extensions will be present in Joomla 4 testing area that MM4 creates.

Remember, updating those (and other) extensions to the latest J4 compatible version is something you do before or after the migration test (depending on the requirement of each extension.)

Does migrateme 4 also migrate the website files and mysql databases?
How does it handle a website that was built using the Protostar template which is no longer supported in Joomla 4??

Hi Robb,

MM4 creates a staging area for a regular Joomla 4 Migration of your Joomla 3 site to take place in. So it doesn't change what happens when the migration happens - it creates a staging site with one click where you can test the migration and fix anything you would have had to fix anyway with a normal, core migration. With MM4, however, once you have your J4 ready to go live you can do so with one click, replacing your old Joomla 3 site. And of course if you discover something in your J4 migration that you wish you had done differently in your Joomla 3 site before migrating, you can abandon the J4 migration, do what you wish you had done and run the migration again.

So in answer to your question, the files and database of your Joomla 3 site are all migrated. When the Joomla 3 site is using the J3 default Protostar site, the Joomla 4 migration then switches to use the Joomla 4 default Cassiopeia template.

I hope that info helps. Just ask if you have any more questions!

Hi Barnaby,
Installed MM4 after uninstalling Akeeba

I changed PHP in Siteground cPanel to PHP 7.4 before creating dev site from Akeeba backup file from a live Joomla 3.10.2 PHP 8 site to a dev PHP 7.4 site.

I get this error in MM4 site

Call to undefined method Joomla\CMS\Application\AdministratorApplication::isSite()

Please assist?

Thank you

Hi Derek,

Thanks for your message!

The isSite() function is specific to Joomla 3, so it means one or more of your extensions hasn't yet been updated to Joomla 4.x.

After running the migration, please ensure the latest Joomla 4 version of each extension - including the template - is installed, and all will then work well.

Best wishes - Barnaby

I installed MM4 first then as per instructions I should upgrade 3rd party etensions. Of course I cant upgrade any extension at this point because I have a fatl error
0 Call to undefined method Joomla\CMS\Application\AdministratorApplication::isSite()

So your installation instructions dont work in that sequence
4."Log into Joomla 4 and update 3rd party extensions."

The only way I can see this working is to update all extensions first then install MM4?

Please clarify and or elaborate?

Thank you

Hi Derek,

We have seen this before when even after using safemode in MM4 (which disables all non-core extensions) an error prevents you form logging into the admin. In once instance the admin module for a very popular shopping cart system had been updated to its latest version in Joomla 3, but it still had had deprecated code that broke Joomla 4 admin area.

Here is a video from the Joomla.org YouTube channel which shows the steps to work around that error so you can login and continue the migration work - https://www.youtube.com/watch?v=ZO9nmdsLlFw

However, if you would like further help with that please email me at [email protected] and I will be glad to get you going.

We're also interested in knowing what file the error was in so we can add that to our experience so we can help others who run into the same issue migrating their site with or without MM4.

Hi Barnaby,

First of all, thank you for you great work! Your component works really well and it saved me days of work. I migrated already 26 websites from our schools to Joomla4 and it works! Really happy with it. If people just deïnstall the components/plugins that doesn't work with Joomla4 and reïnstall after again, everything works fine.

Can you only tell me, how I can get the update when the component is updated?

I am going to be migrating my site in the next few days. I have access to cPanel and I also have a staging development site built. Should (or can) I use that to test the migration first or would it just be easier and simpler to remove the staging site and run your component directly on my live site? I make daily backups so I can restore everything if something goes wrong. Thanks for your insight!

First question:
Will Migrate Me 4 work in a "localhost" environment?
I'd like to convert from J-3.10.10 to J 4.x on my localhost to work through getting all of my extensions and my template ready for J 4.x. I'm running XAMPP for the localhost and and Joomla is installed in its' htdocs folder.
Second question:
Does MM4 create a sub-directory of public_html like your stageit product does so that I could run J 4 from that sub-directory until I am ready to go live?

Hi James

Yes you can run all my software in a localhost environment on XAMPP / MAMP / WAMP etc.

Just make sure your environment is correctly configured, i.e. all PHP extensions are installed etc., and it'll work best on PHP7.x rather than 8.x since 8.x isn't fully supported by Joomla 3.x.

Yes MM4 is similar to StageIt, and runs in /mm4/. Ideally you'd use the inbuilt Go Live function to make the new environment live - this backs up and removes the old environment, and copies the mm4 environment to the live folder.

I have your MMP- Gold installed on my J3 Live and StageIt sites. Do I need to uninstall these before I install MM4 on my Live site? Maybe MM4 will overlay the MMP- Gold install.

Hi James,

If you're migrating Joomla 3 > 4 you won't need MigrateMe Plus, so you can safely remove it prior to running MigrateMe 4...

However, if you really want to keep both in place, you can - MigrateMe 4 creates a different environment to MigrateMe Plus, so they won't conflict - obviously though, once you've run MigrateMe 4, you can't then run MigrateMe Plus.

Hello,

Please install the latest version of your plugin, and ensure it is Joomla 4 compatible.

Alternatively, rerun MigrateMe 4, but first - in configuration - set Safe Mode: Yes, and run the migration. This will detect and disable any potential problem plugins and extensions, so you have a working Joomla 4 environment.
