I did mention this at least a couple times at JES2 SHARE sessions. The good
news is that there's a JES2 migration guide on the z/OS 1.7 DVD; the bad news is
that it's for JES2 1.5. How useful! By the by, the JES2 1.7 Installation Exits
book needs to be read with a salt shaker nearby, e.g. R11 at entry to exit 52
does not really point to the HCT...

is the only salvation for us JES2 folk.

Please join with me in complaining to IBM that there are no more
migration guides for z/OS JES2 and JES3, beginning with z/OS 1.7. These
_extremely useful_ books were "scrapped" because some "genius"
erroneously believed that the "z/OS 1.7 Introduction and Release Guide"
would provide equivalent information. See for yourselves, it doesn't
even come close!

AFAICT, all of that great JES2/JES3 migration information has been lost!
And, at the worst possible time too! (Look how much JES2 exit rewrite is
required due to the extensive JES2 infrastructure changes in z/OS 1.7
needed to support large data sets and TCP/IP over NJE! JES3
installations are lucky because no drastic JES3 rewrite was/is needed to
support these features. But there will almost certainly come a time for
them as well.)
The old migration books provided, not just a list of changes and new
features, but guidelines and specific details on tolerating/exploiting
them. They were an invaluable resource! We need them back!
