When you choose to decommission a Gateway, you must change the Gateway to Quiesced state so that no new tunnels or NSDs can be configured on the Gateway. Ensure that you have Operator Super User role to quiesce Gateways.
To quiesce the Gateway and enable self-service migration:
Prerequisites
Before you quiesce the existing Gateway, ensure that you create a new Gateway as a replacement. Assign the new Gateway with the same role and attach it to the same Gateway pool as the existing Gateway. For instructions, see the “Configure Gateways” section in the VMware SD-WAN Operator Guide available at https://docs.vmware.com/en/VMware-SD-WAN/index.html. Also, review the VMware SD-WAN Gateway Migration - Limitations before you proceed with quiescing the Gateway.
Procedure
Results
In the Gateways page, you can see that the Service State of the Gateway has changed to Quiesced.
What to do next
Send decommission notification to Partners and direct customers who are impacted. The notification email provides the migration deadline and detailed instructions on how to migrate the Edges and NSDs from the quiesced Gateway to the new Gateway.
