Now that the secondary appliance is updated, we need to move the primary role from the first node to the secondary node. To do that, type the command below:
18. MUTG

17. 1force ha failoverStep 2: primary NetScaler node
Repeat Step 1 on the first NetScaler.
Force failover again
Now that the first appliance is updated, we need to revert the HA primary role to this appliance. To do that, type the command below:
18. MUTG

18. 1force ha failoverEnable HA Sync

19. set node -hasync enabled
Enable HA Sync 1
set node -hasync enabled
