PHP5 and 4

[mattcrane]

Hi

I am currently running php 4 on my plesk vps but need to upgrade to 5.

There is one site that uses register_globals which will have to stay for for the next few months unitl i launch their new one.

Can i run PHP4 and 5 on the same VPS, i've heard its possible and i do have the option for 4 of 5 when setting up a site on another hosting account i have with another company.

Also is there a charge for upgrading to PHP5. I wouldnt have a clue how to do it myself.

Thank you

I'd like to know as well about how to upgrade. If it's not too bad I could perhaps do it myself, but I also wouldn't mind paying some for it.
