-- Migration of a database with version 2 of the schema to version 3.
--
-- Version 3 appeared in revision 084d740b1da635946d153475156e335ddfc4aed6
-- and its changes were:
--
-- * Removal of historical data.
--
-- Because from v2 to v3 we went from a unified database to many separate
-- databases, this file is parameterized on @ACTION_ID@.  The file has to
-- be executed once per action with this string replaced.


ATTACH DATABASE "@OLD_DATABASE@" AS old_store;


-- New database already contains a record for v3.  Just import older entries.
