Migrate to New Cluster

[Ekin Gumus]

Hi all,

Planning to migrate production servers (CUCM, CUC, UCCX and CER) to new cluster with same versions. So what I am going to do is create new servers with same versions as in production and recovery from back to servers on new cluster. What steps I need to follow up?

Current versions are 9.x

Thanks.

Ekin,

when you mention "new cluster". do you mean as in new IP addresses?  

have you considered moving the current servers to a new ESX host?

Dennis,

Customer wants to create new servers with same IP addresses, they dont wanna move production servers to new esx host. So what I need to is now, create new servers with same IP addresses, of course they wont be reachable at first to avoid IP conflict. then make the IP phones registered again without any problem. I already did once from MCS to UCS migration but not sure from UCS to UCS.

Not sure what problem you might have, a DRS restore is the same on any platform as long as you meet the requirements, just make sure you do this on a separate network to avoid duplicate IPs and hostname.

Hi Ekin,

The process that you mentioned is correct. DRS backup from existing cluster, reinstall same version on new host followed by DRS restore and cluster reboot. Once the new cluster is up and running you can shut down the existing one and ensure the endpoints are able to reach the new cluster. You may check the CUCM 9.x Migration and upgrade guide for more info

OK, 

I am sure they have their reasons, in that case like manish suggests, approach it as a system recovery to your new servers
