I would suggest that you define 3 guest machines on your z/VM 5.2. Run
your VSE/ESA 2.6.3 systems in two of them and your VM/ESA 2.4 system in
the third. You will get much better performance that way than running
the VSEs third level.

Thanks for the input everyone!
We're looking at getting off our 9221 box running VM/ESA 2.4 and VSE/ESA
2.6.3. We have merely two VSE guest machines and just a handful of
programmers that use CMS for developemnt purposes. No Linux, no production
VM guest machines other than the VSE guests. In our shop, VM is merely
a "hyper-visor" for our VSE guests. However, our programming staff does
not want to lose the various EXEC's they use in CMS and XEDIT.
We have a proposal to move to a z/890 processor to run z/VM and z/VSE to
stay in support. To ease our migration, I would like to bring up VM/ESA
2.4 as a second-level guest along with one or both of the VSE guests under
that, and progress from there. Even at the entry level configuration of a
z/890, its processing capacity is easily twice that of our current 9221
utilization, so I don't think I need to be too concerned about processing
overhead.
I've asked IBM about this and I've not been given a definitive answer. The
latest FAQ that IBM has provided on their z/VM site states that z/VM will
run VSE/ESA and VM/ESA as guests. The "Tell-All" for me would be to find
out if anyone has attempted or done this kind of migration.
So with that said, if anyone has any further information or experience in
doing a migration of this type, I would be very grateful for your input.
Thanks again!
