/* MIGRATION TO COPY LOGIN_SERVER DATA
 *
 * This migration copies all existing data from the `login_server` database (`gradido_login`)
 * to the `community_server` database (`gradido_community`) in case the login_server database
 * is present.
 *
 * NOTE: This will fail if the two databases are located on different servers.
 *       Manual export and import of the database will be required then.
 * NOTE: This migration does not delete the data when downgrading!
