Upgrading 11.5.1 to 13.1.0.6

Upgraded the standby unit, no problem. Then the two units were in a disconnected state and it won't let me fail over to the standby due to a software mismatch. How can I get the standby to active so I can upgrade the first unit? Surely there is a way to force the standby into active?

 

Thanks all!

    Ah! Many configuration changes has added between V11.x to V13.x. Hope you have gone through release notes. If not, no worries.

    Options 1(

    Not Recommended
    )- Make Active unit out of device sync group, So both will become Active-Active. In that case easily you can make one unit offline and install image & hotfix(v13.x) and later add in device group. But its tedious process and outage time will more then expected.

    Option 2(

    Better Approach
    )--> Go to 11.x to 12.x in different partition and validate the configuration(i.e Virtual, Pool, Interface, Memory, cpu,etc )in both unit(Active & Standby). If all is well then boot to V13.x partition.

    Hope issue will solved.

    Hi Expert, Please add your inputs.

    No need to go from 11.x to 12.x to get to 13.x. One can go from 11.x to 13.x directly. See: https://support.f5.com/csp/article/K13845

     

    Check that the 13.x unit has loaded it’s configuration completely by running the command ‘show /sys mcp-state’. This command should return something saying that the config is fully loaded.

     

    Try to login to the active and select ‘force to standby’.
