Nexus 1000V VMotion between 2 different 1KV Switches

Question

Hello Virtual Experts,
I was informed that you cannot Vmotion from one N1kv in one domain ID instance to another N1kv in a different domain ID. 
As I understand, every Nexus 1000v switch needs to be in its own domain. 
If this is the case, how does Cisco facilitate VMotion between switches?  How does Cisco facilitate long range Vmotion?
Any response is much appreciated.

Robert,
You are correct, just as with any vDS and a standard vSwitch you can't VMotion them between (while the Network interfaces are connected anyway).  VMotion will fail the Network Port Group validation.  The networking is what is tripping you up here, and it's not specific to Cisco, it's a VMware validation requirement.
With long distance vMotion, the VMs are still part of the same DVS so there's no issue here. 
You have a couple options here.
1. You can do a cold migration, then re-assign the network binding on the destination switch.  This would require VM downtime.
2. If going from a Host connected to a vDS to a Host using a vSwitch, you can create a temporaty vSwitch on the source host, create the Port Group with the same name as the Destination host's Port Group, give it an uplink and then migrate it that way from there.  This can be done online w/o downtime of the VM.
Not sure of any other methods, but if anyone else has an idea, feel free to share!

Robert
