My IT guy has a server running Red Hat ES5 that acts as a webserver with j1.5. I want to move from j1.5 to j2.5 but that requires php 5.2 or higher. We are currently running PHP 5.1.6 (cli) (built: Feb 2 2012 08:25:26). Even though this is the latest from Red Hat, Joomla still wont load so it needs to be replaced with 5.3. My IT guy noticed that Red Hat has php53-5.3.3-1.el5_7.6 that he can select to install, but it 's telling him that "php53-common conflicts with php-common"
We are thinking we need to uninstall 5.1.6 and then install 5.3.3. Is it as simple as uninstalling the old and installing the new? Will we need to make changes to the php.ini so that Joomla runs without breaking? We want to keep all the RPMS red hat.
I believe that you will need to remove all the old php packages and dependencies and install php53* packages. Note that you will also need to remove old packages for MySQL also and replace them with packages for php53
Upgrading php on redhat can be really tedious process and I would strongly suggest you to create full system backup before you proceed. Also, if you can, try to make this upgrade on one stagin server first to see if everything will be done correctly
