When you restart the database now on maching B, you will
get a new DB-Identifier for this database-instance. The DB-Identifier
is saved in the data-devspaces and in the log-devspace.

Because the DB-Identifer of the migration-backup (from A) does not
match the DB-Identifer of the Log-Devspace (from B). You should
run an "init config" before restoring the backup.
