php5 Upgrade for Plesk 8.3 os_RedHat el4

[FuzzyJared]

I have a VPS that is running Plesk 8.3 with os_RedHat el4. The hosting company stated that they could upgrade PHP 4.3.9 to the PHP 5.2 for a fee, but stated that they could not gaurantee that this would not break Plesk.

Anyone have any advice on this? Is there any easy way to perform the upgrade myself? I am a fairly seasoned web developer, but don't have my chops with server management.

Help and suggestions appreciated.

php5 is not available throught the red hat network channel for RHEL4. We had to move to RHEL 5 vps.

4->5 php upgrade cxan be really painful. a special component, psa-phpX-configurator is required for this. X stands for 4 or 5 correspondingly. Actually if you have this package installed (without forcing) after php update - 80% of the upgrade business is done. rest 20 are for minor configuration issues on domains.

Ive got PHP 5.2.5 rpms in my yum channel for rhel4/5, centos 4/5, and Fedora 4-9. Its not a difficult upgrade at all. The biggest issue is with the new behavior php_admin_value introduced in 4.4.8 and 5.2.5.
