At a minimum, we gotta know what version you are *ON*...
For starters, you should *WARN* your clients of the impending upgrade.
Then *THEY* can prepare any known issues like register_globals etc.
Make 100% sure that you also keep all the extensions to PHP you already
have. Maybe add a couple more. Maybe upgrade the old ones while you are at
it.
You *ARE* going to install on a DEVELOPMENT box with no customers and test
first, right?
Do a backup of the PRODUCTION box before installing, of course.
Upgrade very early Monday morning so that corporate customers:
A) Don't lose a lot of stuff if you need to back off to your backup
B) Are coming in to work anyway, so any problems you've created are solvable
at their work-hours, not 4 am on a Sunday.
Most sites can be down for a few hours and just blame it on network errors
or something... Though if there are mission-critical sites on that
server... Well, you ought to have roll-over fail-safes in the first place,
right? Upgrade one at a time, and be ready to roll-over fast.
Put yourself in your customer's shoes and ask yourself all the worst "What
if...?"s
