Hoping someone will know the answer to this.
Is the version of Integration Services on Hyper-V 2012 R2 backwards compatible with Hyper-V 2012?
The reason I ask is that we are in the process of moving VMs across Hyper-V clusters due to a company buyout, and we've found that networking does not work for guests that have been moved over to the new 2012 R2 cluster until IS is upgraded.
If we could install the 2012 R2 version of IS on the guests while they are still on the 2012 host, it would make moving the machines easier.
