    Migrate vmnic from Nexus 1000V to standard switch: no connectivity

      Hi all,


      We want to get rid of the Cisco Nexus 1000v switches in order to upgrade the hosts, but are struggling with the migration. I create a new standard switch on every host that is connected to the 1000v, with corresponding port groups including VLAN ids. I can migrate one of the physical nics from the 1000v to the standard switch, but as soon as I migrate a vm on that host to the same network on the standard switch, that vm loses all connectivity.


      I have the feeling it has something to do with VLANs but I am no network guru... On the migrated vmnic I can see the IP ranges and the VLAN id so that seems ok. On the other hand, I don't see that information on the vmnic that is still on the 1000v.


      I also tried this with a new DVS but I get the same results. And then I have to do a second migration because moving hosts to a new vCenter with DVS is not supported.


      Does anyone have an idea what could be wrong?
