    1. SSH to new vSDS 9.0.X NOAM and run the following commands to disable the upgrade barrier feature:
      iset -fvalue=1 IdbParamDef where "param='IdbDisableUpgBarrier'"
sudo init 6
    2. Log in to Active NOAM GUI.
    3. Navigate to Status & Manage from Main Menu, then select Server.
    4. Select Standby NOAM server and click Restart.
