We are planning to upgrade a Cisco Call Manager Publisher node from 8.6.2 to 10.5. We want to install a new publisher on a new environment, but we are struggling with some questions.
If we install the Pub node 10.5 can we migrate the configuration from the 8.6.2 to 10.5? Do we need a special tool for this?
If above doesn't work, we can still migrate the existing call manager towards the new servers and start the upgrade, the only problem we face there is that we have to change the publisher's IP because we want to use a new ip addressing scheme.
Your best bet is to use the new tool: cisco prime collaboration deployment. This fits perfectly into what you want to do here and can easily help you with all aspect of the migration including the ip address change. You can learn how to use the tool here..
The only thing I would add is that the tool is not error-free and some things may not work as you expect. In our case, creating the publisher was a simple task however we faced some difficulties with a subscriber. We had to do it completely separate. Make sure you ask for the proper OVA if you are deploying in a virtual environment.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
