How many users and is this a new domain move?
What if you created a new temp HA BES 5 pair of VMs and migrated your users
like you mentioned to the vm pair and create a secondary HA BES pair with
your 4.1 physicals with a different BES names as your new permanent pair and
just do the standard BES 5 moves between your primary vm BES to your physical
BES. When completed the BES to BES move, the VM pair it can be removed from
BAS. Crisscrossing active and passive vm to passive and active physicals seems
a bit more complex but then again I have not worked with vms in BES 5 to that
level

Subject: [Bes-admins] BES 4 to 5 migration question
Date: 2/18/11 6:16 PM
Anyone see a problem with the below plan? The goal is to upgrade our BES 4.1
system without compromising our existing passive BES4.1 failover server for any
length of time.
Set up two VM's for BES 5. One is the passive for high-availability.
Migrate users from BES4.1 physical server to active BES5 VM.
Wipe the BES4.1 machine and install BES5 from scratch. Also wipe the other
BES4.1 physical failover server
Disjoin the passive BES5 VM from the active BES5 VM.
Attach the active BES5 VM to the newly installed physical BES5 server.
Manually fail the users over from the active BES5 VM to the passive BES5
physical server.
Disjoin the BES5 VM (now passive). Attach the Active BES5 physical server to
the newly installed BES5 physical passive server
Thanks,
Stefan Abash
