I'm running a VPS with centOS, plesk 12 and PHP5.3. I'm looking to upgrade to a more recent version of php but without taking down all my sites running on that server.
I've tried through the plesk GUI and got to this point which is ambiguous to what it will do. Is this the way to do it or will it delete my version of php 5 and replace it with something unknown?
Thanks for your help
