Hi,

No there is no impact to current data plane operations, but you won't be able to make any chances. This includes connecting new VMs to segments, reconfiguring of the VM's network, vMotion of VMs, etc. You basically end up with a static NSX environment. It's a pretty bad situation, but perhaps not catastrophic.

Just be aware that after 24h of managers down entries are flushed in ESXi hosts and then you do lose data plane.

This 24 hour limit was removed from NSX-T 2.4.1.

That's right! Thanks
