Hi faizan,

 

The license reactivation interrupts the traffic.

 

So I recommend you to do it in this order to limit down time :

 

  • first do it on the standby device (secondary device), As it is in standby mode it will have no impact. Then upgrade this device.

     

  • once you upgraded the secondary device you will need to manually failover on this device. After that you can reactivate the license of the primary device (standby)

     

In this manner the license reactivation will have no impact on your cluster because each time you've done it on the standby unit.

 

Hope it helps

 

Regards
