This step checks that the topology that was migrated is realized in NSX-T.


  1. Click Start.
  2. In the confirmation dialog, click Migrate and wait for the process to complete.
  3. If the status is Successful, click Continue to go to the next step.
    If you are migrating to ALB, perform the tasks mentioned below before clicking Continue.
  4. If the status is Failed, the details of the failure are displayed. Click Rollback to resolve the issues.


If this step is successful and you are migrating NSX-V load balancer to Advanced Load Balancer (ALB), perform the following tasks on the Avi Controller before continuing to the next step:
  • Validate all the networks for each cloud.
  • For a DHCP network, validate the placement subnet (for VLAN only).
  • For a non-DHCP network, add the placement subnet and static IP range for the Service Engine.
  • Update the segments in overlay cloud for each added tier-1 gateway.
  • Make sure that all NSX-T clouds are in placement ready state.
