   Because the FreeBSD port is still on 1.10.0, I ran into this when I upgraded. Is there a way to recover from this? I'm the only user of my homeserver, there are not a lot of rooms to restore

   I kinda got my HS running again. What I did is:

   • backup my database before doing anything
   • update the room_version in the rooms table to be 1 when the field was NULL to get past this error
   • try to rejoin all the rooms¹
   • delete the entries in current_state_events for rooms I could not manage to join
   • re-join those rooms

   Right now I'm figuring out other conflicts in the database, mainly in *_historical tables

   curl -X GET 'https://HS/_matrix/client/r0/joined_rooms' | jq -r '.joined_rooms[]' | while read r
   do 
     curl -X POST "https://HS/_matrix/client/r0/join/$r"
   done
