CUCM Upgrade 7.0 -> 8.6 and move to virtualized

Hi,

I have to do an upgrafe of existing CUCM 7.0 running on cluster of MCS-7825-H2 to virtualized 8.6 on UCS.

Latest possible on the MCS-7825 is 8.0 and 8.5 only for bridged upgrade.

What is the recommended approach? I can not find it in any document.

CUCM Upgrade 7.0 -> 8.6 and move to virtualized

Hi Blazarov,

This will need to be a multi-hop migration path. The first pahse will be to move

your 7.0 build to a build supported on a virtual deployment. So, for example,

you would probably need to go from 7.0 to 7.1(5) then to 8.0 or 8.5 (using the bridge path)

and at this point you would move to the virtual build.

The high level steps are shown below; Step 9 discusses the need to re-host

your licenses after the migration;

Migrating To Cisco UCS C210 Rack-Mount Servers

#

Migrating from a Media Convergence Server (MCS server) to a Cisco UCS C210 Rack-Mount Servers server follows a procedure that is very similar to replacing server hardware, which is described in the document Replacing a Single Server or Cluster for Cisco Unified Communications Manager.

#

Table 5 provides an overview of the migration process and references to other pertinent documentation.

#

Step 1 

#

Review the document Replacing a Single Server or Cluster for Cisco Unified Communications Manager.

#

This document describes how to replace server hardware, which is very similar to migrating from an MCS server to a Cisco UCS C210 Rack-Mount Servers server. You should perform the document's pre-replacement and post-replacement tasks, and review the procedures for installing Cisco Unified Communications Manager and migrating data.

Replacing a Single Server or Cluster for Cisco Unified Communications Manager

#

Step 2 

#

Upgrade the MCS server to Cisco Unified Communications Manager Release 8.0(2) or later.

#

Cisco Unified Communications Operating System Administration Guide

#

Step 3 

#

If the UCS VM will use a different IP address or hostname than the MCS server, change the IP address and hostname of the MCS server to the values that the UCS VM will use.

#

This is required for DRS backup and restore to work.

#

Refer to the topic "Changing the Cluster IP Addresses for Publisher Servers That Are Defined by Host Name" in the Changing the IP Address and Host Name for Cisco Unified Communications Manager guide.

#

Step 4 

#

Perform a DRS backup on the MCS server.

#

Disaster Recovery System Administration Guide

#

Step 5 

#

Use the Answer File Generator to generate a license MAC for the Cisco UCS C210 Rack-Mount Servers server. The license MAC is required to obtain licenses for the server.

#

After you obtain the license MAC, you can rehost the licenses for your new server.

#

Step 6 

#

Create the virtual machine (VM) on the Cisco UCS C210 Rack-Mount Servers server that will be used as the replacement for the MCS node.

#

#

Step 7 

#

Install the same release of Cisco Unified Communications Manager on the Cisco UCS C210 Rack-Mount Servers server that you installed on the MCS server.

#

Step 8 

#

Perform a DRS restore to restore the data backed up from the MCS server to the Cisco UCS C210 Rack-Mount Servers server.

#

#

Step 9 

#

Upload the new licenses to the Cisco UCS C210 Rack-Mount Servers server.

#

If you did not obtain licenses for the new server already, you must request the licenses first.

#

Note The previous license will no longer be valid. However, you have 30 additional days in which to use your previous license. Refer to "Obtaining Rehosted Licenses When You Change License MAC Parameters" section.
