You can move an ESXi host transport node from one vCenter Server (VC) to another, and also from one NSX Manager cluster to another.

Scenario 1: VC1 connected to NSX Manager cluster 1, and VC2 connected to NSX Manager cluster 2

Assuming ESX1, an ESXi host transport node, is in VC1, you can move it to VC2 by performing the following steps:
  1. Uninstall NSX from ESX1.
  2. Move ESX1 to VC2.
  3. Apply a transport node profile to ESX1.

Scenario 2: Both VC1 and VC2 connected to NSX Manager cluster

Assuming ESX1, an ESXi host transport node, is in VC1, you can move it to VC2 by performing the following steps:
  1. Uninstall NSX from ESX1.
  2. Move ESX1 to VC2.
  3. Apply a transport node profile to ESX1.

Scenario 3: VC1 connected to NSX Manager cluster 1

Assuming ESX1, an ESXi host transport node, is in VC1, you can move it to NSX Manager cluster 2 as a standalone host by performing the following steps:
  1. Uninstall NSX from ESX1.
  2. Add ESX1 to NSX Manager cluster 2.
