We moved from VMS 7.1 to 7.3 recently. Powerhouse remained on 7.10G3.
The VMS upgrade was relatively pain-free, and there were no PH-related
issues.

VMS issues: the new XFC caching is seriously flakey and should be turned
off: stick with the old VIOC caching (VCC_FLAGS=1).
If you're using GoldFax, don't reinstall the ancient & venerable DCE 1.3
that comes with it - DCE is now up to V3.0, and gets mightily confused if
you downgrade it that far.
TCP/IP - we moved up from 4.2-2 to 5.1 at the same time - is a little more
painful, but there's plenty of ECOs out now.

Some nice RMS enhancements (no query locking) which ought to help PH along,
but I've been too busy to benchmark.

7.2-2 is billed as the 7.2 final version, for folk that don't want to move
up from 7.2 or 7.2-1 to 7.3. I chose to skip 7.2 altogether & go for 7.3
(it's obviously going to have a longer support life).
