Migrate CUCM 8.6 VM to 10.5 VM using Prime collaboration

[Mikeb]

We're changing the hostname and IP address during the migration to a new VM, will there be any down time on the existing CUCM? Can this be done with out any business impact?

[Jaime Valencia]

No, the install of the .cop file that enables the migration doesn't require a reboot and the data migration can be done on an active cluster, depending on your CPU usage, you might still want to have a maintenance window to avoid any high CPU issues. As the upgrade itself, it uses resources to export all the config DB and CAR DB.

Cisco Prime Collaboration Deployment simplifies the hostname and IP address change procedures. Hostname change refers to the changing of a server network hostname identity, an IP address, or both. Historically, changing a server hostname involved a series of steps that required the use of the CLI and web graphical user interface (GUI). It also required the user to reboot single servers and whole clusters after the event.

All the existing steps in the procedure "Changing the IP Address and Hostname for Cisco Unified Communications Manager" are automated into a single step using the CLI or GUI. The single-step includes a readiness and post-task list for user verification.
