Over New Year's weekend we migrated a VM/ESA 2.4.0 system (heavy CMS app usage) to z/VM 5.1 (sadly z/VM 5.2 showed up the day before migration -- too late to use it, but that's in progress starting Monday). We were running on a z800 so we did not have to change hardware platforms (although we had to set up another LPAR in which to test z/VM 5.1 since it requires 64-bit addressing which VM/ESA could not provide).
We made sure all the ISV products were current before allowing users to test. - All IBM products were upgraded (except DFSMS RMS for an IBM VTS where we have a beta-test of the code shipped in z/VM 5.2) - We had the Network associates go through the TCPIP config with us (several changes). - Our VM/ESA CP exits were re-assembled, but did not require any refitting (coded per standards the first time). I've been warned to very closely examine CP exits to ensure that they conform to z/VM 5.2 standards. - There was nothing in particular that was any different from previous releases (merging directories is always a difficult issue that cannot be resolved too far ahead of time). - System stability has been the expected and usual 100%. No outages. Good job IBM! - I think we have opened only one PMR for a minor problem with FTP (which has always been there, but just discovered). - As always, do your homework. Check the Installation Buckets and PSP buckets. Mike Walter Hewitt Associates The opinions expressed herein are mine alone, not my employer's.

For those of you having done this, are there things outside the normal course of action I should know? Success stories are also welcome. Any problems with SFS, TCPIP, VTAM, VM:Secure, DYNAMCMS, etc??
