Ah, we need to do a better job documenting this for sure. I think you _cannot_ do an in-place downgrade because the on-disk header format changed to v7 to include some metadata needed for the purge feature that was re-introduced in 2.3.0:

Bill’s suggestion of replication is probably going to be the way to go here. Someone more familiar with the disk format version changes and upgrade / downgrade logic might correct me, but this is my current understanding.

Have you tried replicating your data to the 2.2.1 DB?
