I am using centos 5.2 x64 for plesk 9.2. The current version of php for centos is 5.1.2. I would like to upgrade this to latest version but do not want to risk breaking plesk. Would it be possible to upgrade the php version using atomicrocketturtle repository? I have installed ART and using yum can see the latest version is 5.2.9. Can I use yum to upgrade this php? Would it break plesk? Any other method to upgrade without breaking plesk? Thanks.
