LTM firmware upgrade 11.4.1 to 11.6.1

Looking for any advice on the above upgrade in particular:- 1. How long does it take to reboot and install 2. Have active-standby pair-assume upgrade standby then force to active and upgrade other-does the device and traffic group always remain in tact or is rebuild required 3. After one unit is upgraded does the pair still function despite different firm wares 4. After 1st unit is upgraded is a configure sync required 5. Any issues - obviously know of sslv3 not in default SSL profiles and read someone monitors were mangled. 6. Any other useful advice

    Plan for 5-10 minutes of reboot time. It should be lesser than this though.

     

    Make sure you check the license check date.

     

    Save configuration in the box and outside of it.

     

    You should be able to upgrade the standby 1st, failover and upgrade the current-standby device.
