"NOTE: Your appservice-irc database files have been imported into Postgres. The original database files have been moved from `{{ matrix_appservice_irc_data_path }}/*.db` to `{{ matrix_appservice_irc_data_path }}/*.db.backup`. When you've confirmed that the import went well and everything works, you should be able to safely delete these files."
