Multiple storage accounts as a proxy for syncing over the local network

if it sees the remote not having an item anymore, it considers it as having been deleted from the remote. Which will also delete it from the local database.

That explains why the existing items disappear instead of transferring to the new account. I guess I would need to modify it so that when the account changes it overwrites everything with the state of the local version instead of trying to merge.
