Upgrade PHP from 5.0.1 to 5.0.5 on Solaris

Hello I have been asked to upgrade PHP to its latest version on a Sun Solaris 8 Server. This server is running Apache2, mysql and vbulletin. I have a couple of questions: Do I have to touch Apache or Mysql? or can I just ./configure PHP? Will the configure overwrite the current installation of PHP? Is it best to save any files before the upgrade? I would be grateful for any help as this is a live server with lots of users who are not going to be that happy if PHP does not work after upgrade. Many Thanks John ---------------------------------------------------------------------------------------- This is a PRIVATE message.
