Current CUCM version is 12.5 with 80 GB disk size, can we upgrade to version 15 by expanding the disk size to 110?

[b.winter]

No. You cannot expand the disk. You need to re-deploy and install the Node from scratch (Check out "Fresh Install with Data Import")

[kgareis]

Unfortunately, no. When you expand the disk size, all of the additional space is automatically allocated to the common/logging partition. As a result, your "active" partition, which is where the CUCM OS resides, will remain the same and be inadequate.

You will need to:
1 - Backup your current 12.5 cluster.
2 - Create a new virtual machine using the defined/necessary specifications (CPU/RAM/Disk):

3 - Install your current version of CUCM 12.5 on the new VM.
4 - Restore from backup on the new VM.
5 - And then you can upgrade to version 15.

Will CUCM be supported via KVM. We have lots of customers that don't want to run vmware. Any news on this ?

[Roger Kallberg]

No only ESXi is supported.

[Hafthor Hilmarsson O'Connor]

I know that :), I asked will it be supported is a plan in place or shall I just tell me customer to go else where ? 

[Roger Kallberg]

Per the information shared by the BU there are no plans to support any other hypervisor.

[kgareis]

I'm sorry, but no. There is no plan in place to support bare metal installations for CUCM.
