Dear all,
I have a customer which has a 8 node hyper-v cluster running w8k r2 and all the VMs are also w8k r2. However the customer is looking at upgrading the DCs and other applications and members servers to w12k but I have advised them to also look at their cluster servers.
The customer has enough capacity on the cluster to start building w12k DCs and then depromo the w8k DCs out (note there is one physical DC) They can also start building new member servers and cut over applications and data and eventually move away from having any w8k r2 servers, except the hyper-visors. The hyper-visors are running w8k r2 and are on the same domain.
I have advised the customer to look at upgrading OS on the hyper-visor and also the servers (hardware). The obvious reason I can provide at this time is the life-cycle of the OS and server hardware, however the customer does not feel this out-ways the cost saving if they were left as they are. Therefore I would like some advise on whether this type of setup and some strong arguments for using w12k hyper-visors appose to w8k r2.
