Upgrading from Joomla 1.5 -> 3

[Spikes]

Hello all,

I have a question. The server I am currently working on is on PHP 5.2 and Joomla 1.5.26. I'd like to migrate or slowly move over to 3.0 on the same server however 3.0 requires at least 5.3 (would go to 5.4). In my cpanel, it tells me "PHP 5.4+ Incompatible Applications Installed". Is it not possible to run Joomla 1.5 on PHP 5.4, or are there certain components/modules that do not work with it?

 

The two major third party components I have installed are Community Builder and Jumi.

 

I just don't want my site to explode if I click the button.

 

Thanks,

Rob

you can and should test the combinations you want to try on a localhost development system. you would only put the final tested changes onto the live server once you know they work and only if you have a known good backup of all your existing files and database tables from the live server, should you need to restore them if something does go wrong.

 

php5.4 did finally remove a number of the problematic php features that would require code dependent on the features to be rewritten to both function at all and be properly secured. the things that have been changed in php over time can be found in the php.net documentation migration appendixes.
