[cisco-voip] 12.5 Migration/Rename/SBD

[Schlotterer, Tommy]

Both clusters need to be up and running for Bulk Cert Management to work.

If both clusters are not online at the same time, You would need to set the “Prepare rollback to pre 8” service parameter.

There maybe something you can do with the ITL recovery cert:

EXTERNAL EMAIL




I’m migrating some 12.5 servers from old host to new via DRS. Can’t just move the VMs for various reasons.

I’d like to rename the servers, update DNS in the process. Will not be reiping. Will be moving the production subnet to new DC when I cut.

I have a change freeze window where I’ve got several days to restore the backups and make the changes.

All phones are 78XX/88XX.

I know there have been various improvements to SBD over the years. I’m going to use Bulk Certificate Management, but  should I technically have to for what I’m doing?

Mostly just curious, it’s been many moons since I’ve had to do a migration like this.
