So, the steps would be:
1) Create a standard vSwitch containing the same VM ports as the vDS
2) Put host in maint mode
3) Move one 10 GB nic to the vSwitch
4) Migrate the VM ports and the virtual adapters
5) Move the second 10 GB port to the vSwitch
6) Disconnect host from vDS
7) Bring host out of maint mode
8) Migrate VMs back to the host
Now you are ready to disconnect the host, remove it from vCenter and add it to the new vCenter.
And follow the KB articles pertaining to this.
Is this correct?
Thanks again!
