How do I go about upgrading from PHP 5.1.6 to 5.3? I just got a virtual server with Plesk on it and am a newbie with linux/apache/plesk.

ok so I figured out how to upgrade it !
IN PLESK 10!
task & settings -> panel -> updates and upgrades
then at the top of the page there is a button "Updates source and installation settings" click on that
then very important!
change the menu option "Download installation files from" to "Official Parallels Updates Server"
then click "add components" button
you will the be given a list of of options and you should see PHP5.3 support
then click "continue"
and your done !
easy ; ^ )
Via SSH you can just
I believe plesk should just be able to keep up on what php version you are running but not 100% sure.
I believe that 5.3 is not the default version for Centos 5.5 - indeed, looking at a nearby Centos mirror it uses 5.1.5 but provide 5.3 under a different package name (php53). I suspect that trying to run both packages concurrently will cause problems. So I guess the solution would be to remove the current PHP packages and install the php53 packages - or upgrade the entire OS to Centos 6 (erk!).
Centos is essentially a clone of RedHat Enterprise Linux - which has a parallel open development project called Fedora: if you can't find documentation on package management using yum on Centos, then have a look at the RHEL and Fedora docs.
Don't try to do any of this using Plesk.
Plesk do not ship PHP as it’s integrated part, you have to upgrade php outside plesk and plesk won't provide support on it.
Atomic channel create an script to upgrade the php.
You can get the details from the link.
Using atomic channel script you can upgrade the php in plesk
You should upgrade to plesk 10 which includes php 5.3 by default. The latest auto installer also has an option to upgrade php to 5.3. You can find the auto installer at /usr/local/psa/admin/bin/autoinstaller.
