So we have a single server 2008 r2 machine that is running RDS.
We are looking to upgrade this to Server 2012 R2, and from what I have been reading my best way would probably to rebuild.
My main question is what about the cals. As there will be only one RDS server, am I correct that I would have to get the 2012 R2 cals as you cannot "upgrade" the 2008 r2 cals
