I'm using Plesk control panel v10 on a Windows dedicated server.
Plesk 11 will also upgrade PHP version to 5.3, but some of the websites on server do not support 5.3.
Is it possible to have both versions (5.2 and 5.3) after the Plesk is updated?
Are there any steps I should take after update?
Found this article: http://kb.parallels.com/en/113179 but it deals only with upgrading the PHP version, not Plesk version as well.
