You can change port group from vCenter utilizing a vRO Workflow.
1. Select VMs and Templates
2. Right-click a server and select All vRealize Orchestrator Actions > Change_Port_Group_Backing
A new popup window will be displayed with the server input already provided (since you right clicked and ran this workflow from the server, it knows you wish to run this workflow on this object).
3. You will see a list of currently connected NICs (up to 8) and can change each one from a dropdown list showing all available port groups.
4. Click Next, select Run now or Schedule, then Finish
5. You can check the status of your workflow from the task viewer and verify completion.
