Upgrade to 2.11 failed

After following the update instructions… Lost connection to manager port (verified PWs match in both conf files). Amportal restart loops with:

I needed to get PBX backup so reverted to a snapshot, but will try again this weekend. What additional information needs to be provided if same thing happens?
