I asked this in the migration forum, but they pointed me to you.
I have read through the guide to migrate from 2003 or 2008 to 2008R2. I assume the same applies for 2008r2 to 2012.

We would like to upgrade to server 2012 for our fileshare cluster. We will be using the same physical hardware, and same storage. This file server has several shares, each with unique permissions.
The issue I have is that I need to use the same cluster name, same IPs, save virtual server names, and same machine names. the biggest issue being the cluster name and IPs. I cannot do this with the migration path.
Can i do it this way?
1. Evict one node from the cluster. Upgrade it to server 2012. Now I have a single node cluster on 2008R2, and a stand alone server running 2012.
2. For the remaining node, in place upgrade to server 2012. Now i have a stand alone cluster running server 2012, and a stand alone server running 2012.
Add the second node back into the cluster. Now i have a 2 node server 2012 cluster.
Is this supported? Can i do an in-place Os upgrade to a stand alone server running 2008R2 cluster services with fileshares? Any documentation stating that it is supported?
