Hello, everyone,
In addition to the current vSphere farm, I am currently building our current farm, which should be active in the future.
The farm under construction, hosts will be connected to a distributed switch and other hosts will be connected to normal vSwitches.
Now, of course, the goal is that VMotion should be possible from host to host without downtime if possible.
From the hosts with normal vSwitches to the distributed switches it now works properly. However, back from the distributed switch to the hosts with vSwitches, I get a warning and it is not possible.
Here's the message.

As a side info
vDSwitch has version 6.5
Hosts ESXi 7 U3 and hosts with vSwitch 6.5/6.7
multiple clusters
The question is now is this generally not possible or do I have to set up a specific configuration. Unfortunately I mostly only find texts on how to migrate vSwitch to VDswitch and back.
Unfortunately that's not what I need.
Are there any options or do I have to look at a complete vDSwitch network infrastructure so that migration between each other is possible? Or do I just have a board in front of my head when thinking?
