Steps are correct but do on different order.

 

1) Take the backup of both unit.

 

2) Activate license on standby device.

 

3) Upgrade standby device(image n hotfix)

 

4) Validate the behavior of device(memory, CPU, interface packet in n out, etc)

 

5) Failover device from standby to active

 

6) Do the same steps on other node(repeat steps 2 to 4)

 

7) sync both unit.

 

Cheers...
