Plesk 8.2.0 to run PHP4.4.2 and PHP5.2.6? Options

[darkscreamz]

Hi guys,

After finding this handy forum I thought I'd put a call out for some advice on some server upgrades I'm wanting to do (albeit with newbie only knowledge).

Currently we are running:
Plesk 8.2.0 (Red Hat Enterprise Linux ES release 3 (Taroon Update 6)) and PHP 4.4.2.

What I'm hoping to do is run the latest PHP 4.4.9 release and also have the option of running PHP5.2.6 for users requiring v5.

Is it possible to have both of these installed on the server and utilise Plesk to specify what version to default to for each users domain (I would want 4.4.9 to be default), or would I need to go via a method such as .php5 for users wanting to utilise PHP5?

Any assistance would be appreciated :)
