Hey, hope you are doing fine:
If you were to do a cross cluster vMotion please keep in mind the following:
- If vMotion interfaces can not reach each other, vMotion traffic will go trough management interfaces.
- vMotion interfaces should be routable , please consider using vMotion TCP/IP stack.
- The idea of vMotion is for it to be transparent to the VMs, if you have to change the IP's of VMs something is missing.
What you will need to do is to generate portgroups on the destination cluster with the same vlans / or VXLANs to reflect the origin.
Let me know if I can assist you with something else.
Warm regards
