Anyone done an upgrade to Mojave and know if the FP10 continues to work?

I've just taken possession of a couple PreSonus FP10 boxes. I am currently running OS X HighSierra (latest update, 10.13.6). I know that official support by PreSonus stopped a while back. However, coreaudiod services in the OS seem to be working ok.

I know I'll need to upgrade the OS sometime, but I am very hesitant. With the drive to get off of 32 bit into 64 bit only type configurations, it's just a matter of time before backward compatibility will be a thing of the past for equipment like the FP10.
