Hi all,
I have a VM running in the cloud that has an old web/php app (10+ years
old, believe it or not), that still runs fine on apache 2.2.25, but I
pinned php to 5.3 some time ago.
Does anyone see any big potential gotchas (major changes) with php 5.4,
or even 5.5, if I were to upgrade it?
Impossible to say without seeing your php code. Potentially there are
many changes.
You'd be better off doing the heavy lifting yourself first:
1. read all the changelogs
2. run it in a staging vm with php5.5 and see what happens
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...
