CUC 9.1 migration to VM process

I am working on migrating our CUC 8.5 physical cluster to 9.1.1 on VMware, however the documentation doesn't seem to have a clear path for a clustered CUC installation.

 

I am referring to the following document:

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/upgrade/guide/9xcucrug010.html

 

I have upgraded the physical servers to 9.1 per the document, however where the document falls down is how to then migrate to a virtual environment (unless I am missing it).  The document gives directions on how to migrate for a standalone installation, but not a cluster.

 

Is it possible to remove one physical server from the cluster, then add a new VM to the cluster, switch roles after replication has completed (publisher/subscriber), remove the old physical publisher(now subscriber) and add a new vm subscriber?  Then swap roles again if you want to maintain subscriber/publisher locations?

 

I would like to keep the existing IP addresses if possible, but changing IP addresses isn't a deal breaker if I have to.

 

Or is it best practice to break the cluster down to standalone, then follow the document for migrating a physical standalone to virtual standalone?

 

As seems common in this section, please don't suggest calling the PDI helpdesk as I am not a partner.
