I feel v12 is now stable (in our experience). All the v12 introduced bugs that are "production important" to us have been fixed now. I will say there are a few regressions on some issues that we have had to implement manual workarounds for, but I am told some of these things will be addressed soon (for example: the daily control server Postgres database backups have stopped, logging of backups stopped etc)
I don't see the pre v12 bugs have started to be addressed, but I believe that will start soon. So, the sooner you get to v12 the better since you'll want to be seeing the old bugs being fixed for you.
@Adam v12 is very good, not just the resource usage. Perhaps it's been a little nightmare for you (support wise) but I hope things can now return to "normal" for you. Whether the backups on the roadmap for March make it or not, we are ok.. but they are not a huge thing to implement I don't think, so it's possible Enhance may even release those as planned by the end of the month.
Finally, being able to move your control panel is a huge step. Thanks Enhance for getting there finally with this. While you need the current server to still be up and running, it's still a technical possibility now. If you digest the steps provided in the documentation you will also see which files are needed in the case of a DR situation.
