Offline Migration with a Backup location

Diagram of physical offline migration, showing all required components with user applications pointing to the on-premises source database. The source database is connected to a backup location via https, the same way the backup location is connected to the target database.

Online Migration with a Backup location

Diagram of physical online migration with backup location, showing all required components with user applications pointing to the on-premises source database. The source database is connected to a backup location via https, the same way the backup location is connected to the target database. Then, ZDM is connected to both source and target via SSH, and the source database is connected to the target database via SQLnet.

Migration with Direct Data Transfer

Diagram of physical online migration with direct data transfer, showing all required components with user applications pointing to the on-premises source database. ZDM is connected to both source and target via SSH, and the source database is connected to the target database via SQLnet.

Offline Migration with a Backup location
