Hi,
We are in the final stages of our upgrade project. The powers that be want to know if anyone has performed such an upgrade?
Were there any significant problems?
Are there any known bug is z/OS 1.7 that we should look out for? Our current environment is:
Two z890's. Each has a production LPAR and a system test LPAR. The production 
LPAR's are connected in a basic SYSPLEX using CTC's.
Software running is OS/390 v2.10, CICS TS 1.3, ADABAS and NATURAL.

It is unsupported upgrade, so you have to pay special attention to operational datasets upgrade/conversion/use. I mean RACF db, ICF BCSes, HSM, RMM CDSes, JES spool and checkpoint, etc. etc. Theoretically you could re-create them from scratch, but in real world you would want to use existing ones. It can be risky.
