Migrate Failover Cluster from Windows Server 2008 R2 to 2012

Upgrading a Windows Server Failover Cluster to the next version of Windows Server is not one of the easies processes compared to other server roles.  When I was ready to move my cluster to 2012 I looked online for the best resource that I could find to help with the transition.  During my search I found this MSDN article that is as close to a step-by-step that I could find.  There are two different ways to move from 2008 R2 to 2012: Windows Server 2012 Failover Cluster Migration Wizard or System Center 2012 Virtual Machine Manager with Service Pack 1.  I used the Migration Wizard.  In order to use the Migration Wizard, you need to create a new cluster.  I had six nodes running my cluster, to create the new cluster I evicted half and created a new 2012 cluster with them.  I then connected my SAN via iSCSI to my new cluster while connected to my old cluster.  Next I ran the migration wizard to copy the configuration over to the new cluster.  After this step, I took the Virtual Machines and the shared storage offline (in that order) in Failover Cluster Management in the 2008 R2 cluster.  As soon as I did this the storage then appeared in the 2012 management window and I put them online.  Now I am running on Windows Server 2012.
