Cisco UC VM's move to HP servers

[Mohamed Hussain Siddique]

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?

I would upgrade to esxi 6.5 before doing any Vmotion or migration.

As all the moves would be generally contained within VMWare, the process would be the same - regardless of hardware.

You can review the following doc for information on hardware requirements and compatibility for UC applications - https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/collaboration-virtualization-hardware.html

Thanks.

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.
