MaxDB WikiMigrate from 7.3 to higher releases using backups
It is only possible to use complete data backups made in 7.3 with higher MaxDB releases. Incremental data backups and log backups are not supported!
To be able to use backups created with release 7.3 in higher releases, a few extra steps are necessary before making the backup in 7.3.
The procedure is outlined in the MaxDB documentation: ![[WWW]](/wiki/modern/img/moin-www.png){kind=small}

As a shortcut, the most important steps are shown here as well:
In release 7.3:, using dbmcli
Shutdown the database using db_offline (do not use db_stop)
Enter db_cold at the dbmcli prompt
Make the backup to be made ready to be used with higher releases: util_execute migrate at the dbmcli prompt
Enter util_connect at the dbmcli prompt
Start your backup: enter backup_start <your backup medium here> at the dbmcli prompt
Once your backup is finished: db_offline
You now have a data backup that can be used with higher MaxDB releases.
