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.
