CUCM, Expressway & UCCX Migration from Old server to new

[mzee.sidd]

We have a customer who is having CUCM ,expressway and UCCX VMs on (ESXI 5.5) C220 M3 server and they are planning to migrate it on the new server i.e. C220 M5(ESXI 7.0). If we migrate it through PCD then what will be the licensing status of CUCM on the new server post migration or we do the offline setup and do the backup restore on the newly installed CUCM then also what will be the licensing status and how the licensing part will be migrated and how the VMs will be migrated from ESXI 5.5 to ESXI 7.0.  And we have same query for expressway and UCCX, how do we migrate and how can we take care of the licensing part.

You cannot migrate uccx using PCD.

Migration to same version is also not supported by PCD.

I would use vmotion to move the VMs from the old servers to the new. There is no need to go the long way via migration in PCD if all you want out of it is to move your VMs to new hosts, aka servers.

Using vmotion to move to new hosts would not affect licensing at all.

Hi ,

Thanks for the information. And is there any thing else that needs to be taken care for moving VMs from Esxi 5.5 to Esxi 7.0.

Not directly, but the vm compatibility is recommended to be updated on each of the VMs when you have moved it to a new host. The VM should run fine without this, but it would not be able to draw use of all functionality in the newer version of ESXi. Worth knowing is that once you have updated this you would not be able to move it back and run it on the old version.

Possibly stating the obvious, but you’ll have to make sure that the versions of the services that you run is compatible with the new version of ESXi.
