In Cucm cluster we have two cisco callmanager nodes. 1 Publisher and 1 subscriber. Cisco UCM version is 8.0.3. And all phones now registered to subscriber.
Publisher is on MCS-7825H3 (phisical)
Subsceriber is on ESX (virtual).
My is migrate pubsiher from Phisical to Virtual medium. What is the best way you thing about migratin publisher from P to V ?
Because I dont want to affect users from migration.
1) On physical MCS servers 8.0.3, take a DRS Backup of the Publisher
2) On the VMWare where Pub is to be on, do a fresh
install of 8.0.3 on it using the same Hostname/IP Address of the existing Pub.
3) Once you have completed the fresh install of the new Pub on VMWare,
restore the Backup that you took from the old Pub.
4) Build the new Subscribers on VMWare using the same Hostname/IP Addresses
of the existing Subscribers.
Here is some documentation on it:
Hope this helps!
