i'm currently using vsphere 6.5U1 and all the ESXi hosts' vSwitch were configured into two switches: vSwitch0 and vSwitch1
(the hosts' NIC is intel 82599 and each vSwitch utilizing a vmnic respectively.)
the VMs in my infrastructure were all connected to portgroup - "VM Network" on vSwitch0 and working properly.
the question is, i wanna migrate the "VM Network" portgroup(still use the same portgroup name) to vSwitch1(on every hosts) without interrupting VMs' network connection.
is it possible to migrate portgroup to another vSwitch seamlessly? or the VMs must to be disconnected temporarily when i create protgroup and migrate to another vSwitch?
P.S. not talking about distributed Switch
thanks in advance!
You can't lift-and-shift a port group to another switch, but what you can do is create a new port group on vSwitch 1 and use something like PowerCLI to script a mass update on all VMs to point them to the new port group. Assuming this port group is configured similarly and the upstream access is the same, VMs will only experience a very brief reconnection. In some cases, this may only be loss of a single ping request.
