Hi
We are planning to move our Cisco UC (11.5) VM's to HP as our UCS are EOL and we want to utilize our HP servers.
As per discussion
https://community.cisco.com/t5/ip-telephony-and-phones/move-vms-to-new-esxi/td-p/3868023 ,
we will stick to option 2
In this regard we need some clarifications
- Is there any difference in process in moving VM's to HP vs with other Cisco UCS servers?
- Any comparative HP server for Cisco UCS C-server.
- Current VM's running vsphere 5.5 and HP running 6.5 , do we need to upgrade to 6.5 and then move?

Thanks Mike.
Our current cucm version - System version: 11.5.1.11900-26 , we would be retain the same version in the new server. We need to know for any security vulnerabilities with this version and any suggested upgrade within 11.5 X tier.

Hi Mohamed, I hope all is well with you!
There should be no need to upgrade ESXi before you move the VMs. From what I know it should be possible to run a VM that has an older version than what the hosts have, but this should be verified with your server team before you go ahead with the move.
About the upgrade, I would recommend you to go to the latest version of 11.5. As of now that would be SU8. This version would also get you in the clear of the upcoming change to APNs that Apple has announced.

That's correct. One property of each VM is its "Virtual Machine Hardware Version" variously abbreviated depending on where it's shown. This indicates the earliest ESXi version the the VM can run on, they can run on later versions but not earlier. So for example VM version 8 can run on ESXi 5.5 or later.
