Offline Migration with a Backup location

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.
These workflows are supported for Oracle Base Database Service, Exadata Cloud Service, Exadata Cloud@Customer, and on-premises Exadata.

Online Migration with a Backup location

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.
These workflows are supported for Oracle Base Database Service, Exadata Cloud Service, Exadata Cloud@Customer, and on-premises Exadata.

Migration with Direct Data Transfer

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.
These workflows are supported for Oracle Base Database Service, Exadata Cloud Service, Exadata Cloud@Customer, and on-premises Exadata.

Offline Migration with a Backup location

Offline Migration with a Backup location Diagram of logical 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. Data Pump flows for export from the source and import from the target. Then, ZDM is connected to both source and target via SSH.
This workflow is supported for Oracle Base Database Service, Exadata Cloud Service, Exadata Cloud@Customer, on-premises Exadata, and Oracle Autonomous Database.

The source database connected to a Backup Location via https, same way the backup location is connected to the target database. Data Pump flows for export from the source and import from the target. Then, ZDM is connected to both source and target via SSH, and a GoldenGate hub with two microservices (a replicate and an extract) are connected respectively to the source and the target.
This workflow is supported for Oracle Base Database Service, Exadata Cloud Service, Exadata Cloud@Customer, on-premises Exadata, and Oracle Autonomous Database.
