Keithz,
as far as I know, Plesk will downgrade PHP back to 4.3.4 when performing an update. Have you found a way to stop Plesk from doing so? (I’m looking for a solution to that problem myself - any hints welcome
)
I have perfomed the Plesk 7.5.4 update myself yesterday on a 1und1 server running under SuSE 9.1 using the updater from the Plesk CP - no problems so far (in some forums, people report problems perfoming the update). What I like about the new version is the new watchdog module that monitors services like apache, mysql and so on and is able to send alerts as wel as try to restart dead services. The only small glitch so far is a mess for the german language files - for example the watchdog module does not seem to be translated right now (but I use the english interface by default and don’t have users that depend on the german translation.)
