Question on migrating CUCM 8.5.1 from MCS to UCS

[BILL PETERSEN]

Hello,

I am doing a simple migration of CUCM 8.5.1 from MCS to UCS VM's. I know the process of DRS, VM build, restore and relicensing but I was wondering in the case of a simple migration, not upgrade, if there was any preference to doing the subscribers first then the pub of vise versa.

thanks

Hi Bill,

As per the following link

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/8_0_1/cluster/clstr801.html#wp87714

Table 4     Cluster Replacement Process Overview

Step 1

Replace the publisher node.

Step 2

Replace any dedicated TFTP servers or other non-Cisco Unified Communications Manager cluster nodes.

Step 3

Replace all backup subscriber nodes.

Step 4

Replace all primary subscriber nodes.

Hello Bill,

1- Install the VMware on the UCS

2- Then you can easly install the same version 8.5.1 on the UCS

3- Backup from MCS server

4- Restore on UCS

5- Rehost the Licesnes

then you can install your subscribers.

What do you mean with "doing the suberscriber first" ?
