    ThanksMahmoud,

     

    some additional thoughts from the field:

     

     

    Study the release notes for known issues and changed behaviour and cross check with the own setup / environment.

     

     

    Make sure to check the service date, refresh the license and create a backup archive before running the upgrade, please.

     

     

    Verify settings for db keys (liveinstall.*):

     

     

    tmsh list sys db liveinstall.*

     

     

    Have a serial console attached (remaining in the default settings @19.200 8N1 or at least a configured AOM accessible via SSH).

     

    In v11 you can easily monitor the failover state on the remaining unit by running:

     

     

    watch -d -n 1 tmsh show cm traffic-group

     

     

    Keep in mind to update EUD and AOM as well, please.

     

     

    Have a plan for fallback.
