Hi All,
I currently have two nodes running in a Server 2008 R2 Cluster and the time has come to rollup to Server 2012 R2. There doesn't seem to be a simple solution to this, despite a bit of hunting around. I am proposing to do the following:
Live Migrate all VM’s to Node 1.
Evict Node 2 From the Cluster
Removing Clustering Role from Node 2
Complete in place Upgrade on Node 2
Install New Cluster on Node 2
Migrate Existing Cluster on Node 1 to Node 2 (Inc VM’s)
Destroy Old Cluster on Node 1
Remove Clustering Role from Node 1
Complete in place Upgrade on Node 1
Install Clustering Role on Node 1
Add Node 1 to New Cluster on Node 2
Can anyone see any issue with this?
It appears you can In-Place upgrade from Server 2008 R2 to Server 2012 R2 providing the Clustering Service roll is not installed (https://blogs.technet.microsoft.com/chrisavis/2013/10/01/performing-an-in-place-upgrade-of-server-2008-r2-to-server-2012-r2/) & (https://support.microsoft.com/en-ae/help/935197/you-cannot-upgrade-the-operating-system-of-a-clustered-server-from-win).
It also appears you can migrate the 2008 R2 Cluster to 2012 R2 using the Cluster Migration Wizard (https://blogs.msdn.microsoft.com/clustering/2012/06/25/how-to-move-highly-available-clustered-vms-to-windows-server-2012-with-the-cluster-migration-wizard/)
I want to use the In Place upgrade feature so as to retain the networking configuration as the nodes each have a number of connections and there are 4 different networks configured within Hyper-V
Any Ideas or suggestions very welcome.
Cheers
Andy
