Environment

VMware NSX

Cause

This is the expected behavior.
The destination tier-1 gateway must be in the Active-Standby mode.

Resolution

Follow the procedure below to modify the Tier-1 gateway's HA mode and assign an Edge cluster.

1. Log in to the NSX Manager UI.
2. Navigate to Networking > Tier-1 Gateways.
3. Locate the Tier-1 Gateway hosting the load balancer service, click the vertical ellipsis, and select Edit.
4. In the HA Mode drop-down menu, select the "Active Standby"
5. In the Edge Cluster drop-down menu, select the new target Edge Cluster.
6. Ensure the Edge Pool Allocation Size remains correctly sized for your deployed load balancer (e.g., LB Small, LB Medium).
7. Click Save to apply the configuration.
8. Navigate to Networking > Load Balancing.
9. Locate the Load balancer service, click the vertical ellipsis, and select Edit.
10. In the Attachment drop-down menu, select the Tier-1 Gateway hosting the load balancer service.
11. Click Save to apply the configuration.
