They can keep the legacy architecture.

The level is determined by the server with the lowest specs qua
architecture but since it is a cluster property you can add 1 or 2 new
servers in a new cluster which you could use to run the new VMs.
So if all your servers are Nehalem than you'll need at least one new server.

Yes.
