moving a host from one cluster to another

I need to move a host that has running vms from one cluster to another. The source hosts and the hosts on the destination cluster shares commong dvs.

what is best way to do this?

I tried to disconnect and remove the host but lost the dvs and all the vms are now left with a blank network PG. They are all still online.

SO I added the host back into the source cluster and readded the host back into the dvs and still the vms are still left with a blank Port group setting

any idea?
