Preparing for PHP8

With the end of PHP74 set for later this year, I am looking at the prospect of moving to PHP8 (or 8.1, though probably not).

I have heard various stories of many issued with the move to PHP8 and a lot of software not making the transition, so I am wondering how I can check fit anything that I am currently running will work with PHP8 or if I need to find alternatives. I know apache works with PHP8, and I am relatively sure round cube does, but I definitely want to check everything on the system, for compatibility before I make the switch.

As for making the switch itself, since I am still using postmaster (I tried poudriwassits again, in earnest, and nope), is the postmaster -o flag still the best way to replace the old version?
