Upgrading from Joomla 3 to Joomla 4 for dev purposes

Post by jhallshape5 » Tue Jun 26, 2018 10:33 pm

Hello,

I'm in need of updating a Joomla 3.x site to Joomla 4. Is this still possible? My friend did it and now can't remember how and we need to do this to properly test a patch for our templates to make them J4 compatible.

Thanks to anyone who may know how to do this!

Jonah

I got it:

1. Logged into current Joomla (May be Joomla3) administrator, and stay logged in there

2. Upload Joomla 4 package files to site's root directory using any file transfer software or using cPanel file manager. You won't need to upload "installation" folder of Joomla 4. In the case of file manager, upload zip package and extract files on site's root directory, rename "installation" folder name to some other name. This way you have all Joomla 4 files.

3. Add "namespace" column in extension table in your site database. `namespace` varchar(500) NOT NULL DEFAULT ''. Also you will need to edit "checked_out_time" current date to "CURRENT_TIMESTAMP"

4. Run this URL administrator/index.php?option=com_installer&task=database.fix This will fix your database version to Joomla 4 and should all good to go now. Ex. if your site's domain is example.com then you should run this url http://example.com/administrator/index. ... tabase.fix

Sorry but that wont work as you will have files left over from j3 that are no longer used or have been moved to other places

Well... OP asserts it works ("got it").. But Brian says "no"...

Is there an actual workable solution? I have the same requirement... would like to bring my 3.8 site over and 'update it" to J4 to get started on development without having to rebuild the whole site from scratch.


I thought that I read somewhere that 3.9 would be "upgradeable". Is there a 3.9 beta we can use to upgrade a test site from 3.8??

https://developer.joomla.org/nightly-builds.html
To always use the latest version and test the update component you can use this custom update server: https://update.joomla.org/core/nightlie ... r_list.xml
Tried Components >>> Joomla update >>> Options ... 'Custom url' ... https://update.joomla.org/core/nightlie ... r_list.xml
But no avail ?

Tried that - made a little progress!
Well, I was able to properly upgrade my 3.8.12 to 3.9, and then to 3.10 ( test versions).
But the upgrade from 3.10 to 4.0 failed after 86%.

Ooops! I jumped the gun, when I should have double checked the github first. (I just naively assumed that since the upgrade was offered, it should probably work...)
