Hi.

I just really want to double check that what I am about to do wont break everything.

I have a 2 node Hyper-V 2008R2 cluster, with 15 VM's).

I have purchased a 3rd server where I will install Server 2012R2 and Hyper-v.
the idea build 1 server and connect up to the Shared storage. Shut down all VM's

Import them into the New Hyper-V server

Break the old cluster, rebuild server to 2012R2 and create highly available cluster. power on the VM's.

rebuild final server to 2012R2 and then have a 3 node cluster.

Does this seem correct in terms of order or should I switch around any steps

thanks 

The steps seem reasonable.

As far as the hardware, is the third node being introduced newer than the other two?

Unfortunately it is.

we use the HP DL380. the old ones are G8 and I believe the new one will be a G9

Hi Sir,

For cluster , to avoid potential issues Microsoft recommend that you use a set of matching computers that contain the same or similar components.

Actually , G8 and G9 can not meet the requirement "same/similar components" .

Also please refer to the similar thread:

Not sure why you are saying that, Elton.  The G9 has a newer processor, but Hyper-V adapts to that with no problem.  Just make sure all your VMs have processor compatibility is set.

Yes, I agree it is always better to match hardware as much as possible, but that is not a strict requirement.  The best thing to do is to talk to HP about it and see what they say about supporti

Hi Tim,

Thanks for pointing it out , and I agree with your statement of processor compatibility setting .

What I said is around the "MS recommend configuration " .

Also , I posted the similar thread , the other marked reply mentioned "Best practice would be to have the same hardware on the cluster nodes, but as long as your cluster passed the initial tests you should be fine. "
