RE: V2R3 CISC to V4R2 RISC - Do we dare?

[Neil Palmer <npalmer@xxxxxxxxxxx>]

Something that I think PM/400 SHOULD handle during a release upgrade is
to kick off a job that does:
CVTPFRDTA FROMLIB(QMPGDATA) TOLIB(QMPGDATA)  

You STILL need to do that manually for performance data that is kept
from before a release upgrade.

I still continue to find minor niggling problems with PM/400 after
release upgrades.  My latest (V4R1 to V4R2) went in and changed the
schedule times for my Q1PCM1 job (upload data to Rochester) job, and
removed the PMOFF/PMON before/after programs (from the PMLINMON command
setup), so of course when it went to dial out to upload to Rochester the
lines was unavailable.
