The upgrade from 10.x to 11.x is possible, please make sure of below important things to note:
  1. please reactivate the license if 10.x (Service check date) is older than license check date of 11.x.
  2. then take archive and proceed with patching
  3. make sure config like HTTPS_CLASS are removed or converted, especially if 11.x is after 11.4.1 (sol14409: The HTTP Class profile is no longer available in BIG-IP 11.4.0 and later)
  4. it will almost take 10-15 minutes approx. for LB to be reachable/pingable., it might be possible that after boot activation and reboot you might be not able to login with ur creds., then login with root to check if config loaded properly (you may take help of doal command)
