Hi Paul, I did a move from v12 to v15R5 3 weeks ago. Mainly mac clients and an xServe with Accelsior pcie drive. Not so big database as yours, but 30 users and 10 Gb datafile. Mission critical also. Regarding database and stability everything has been running very well. I had to do some changes regarding the web compatibility setting "Remove / on unknown urls". The setting did not change, but in some places logic failed. In the overall picture nothing to bother about at all.
We did have a timeframe round new year so it became v15R5. Not fully updated if 16 is in v16.0 or .1 or if there is a next release R1. I would have chosen the successor to R5 today. Using v15R5 mac and pc, 32 bit, legacy network.
