Actually, I was just thinking of doing #2 on the dev server (no dev 
going on, but I had this set up some time ago when we moved the 
production server to linode, so now at least I can test things without 
breaking the production system), and if it breaks, just downgrade back 
to 5.3...

That assumes, of course...

Is php difficult to downgrade after an upgrade?

Thx Alan...
