We currently have a 3 node DAG with 2 nodes in our primary data centre and 1 node in our DR data centre.
We are planning a move of our DR data centre.
I have been asked if it is possible rather than moving the DR node, to build a new one on Server 2012 in the new location and add this to the existing 2008R2 based DAG
I don't think this is possible, I've seen enough complaints from R2 when upgrading the nodes from RTM to SP1 although it all did keep working, and even if it was it seems like a very bad idea to me but need something in black and white to that effect.
Any takers?
Thanks
Neill
