Re: P7 V7R3 to P9 V7R3 migration recommendations / suggestions

Just to clarify, the Hypervisor controls Memory, CPU, virtual networking
and card assignment (and, if in use, SR-IOV/vNIC).
IBM i or VIOS can act as servers for other LPARS and give them disk and
network.

Are you suggesting NOT to use STRRCYBRM, but to use manual restore
commands?
Can you give an example?

I will agree that a "21" will be faster than a BRMS recovery, without too
much question. That said, as I have pointed out you can use BRMS to do the
back up, then manually restore as long as you use the correct options.
It's
just as fast as a "21" recovery in that case, and as a bonus, you now have
a
complete database of every object on the system, what tape and sequence
number it's on. When the inevitable missed objects drill starts, BRMS will
make the recovery go much easier.

<besides the (usual) tip to NOT use BRMS

This is exactly what IBM support suggested back in 2012.
Don't use BRMS.
Why is this?
What are the details behind using BRMS vs Save21/Restore21.
And that is what I did, Save21/Restore21.

Simple, one option
Quicker then BRMS would have been.

Paul,
besides the (usual) tip to NOT use BRMS, we mostly do migrations using High
availability software. Create SAVE21 of the sources (without BRMS), load
them to the target. Then setup a mirror, wait until mirror is synced, then
do a switchover within some minutes.

Depending on the software vendor you might get a cheap 4 week licensing
option for only a switchover. And if you test the software, you might want
to keep it ;-)

3) Any other migration or recovery suggestions from the group?
