Migration Workflows to Oracle Exadata Database Service
You can perform the following Oracle ZDM migration workflows to migrate you Oracle Database to Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) on Oracle Database@Google Cloud:
Physical Online MigrationThe physical online migration workflow supports migrations between the same database versions and platforms. It uses direct data transfer and the “restore from service” method to create the target database, explicitly avoiding backing up the source database to an intermediate storage location. Oracle Data Guard keeps the source and target databases in sync to achieve a minimal downtime migration.

Logical Online MigrationThe logical online migration workflow supports migrations between the same and different database versions and platforms. It uses Oracle Data Pump export and import to create the target database. Google Cloud Managed NFS Server provides an NFS file share to store the Data Pump dump files. Oracle GoldenGate keeps the source and target databases in sync to achieve a minimal downtime migration.

Physical Offline MigrationThe physical offline migration workflow supports migrations between the same database versions and platforms. It creates the target database using Recovery Manager (RMAN) backup and restore. Google Cloud Managed NFS Server provides an NFS file share to store the RMAN backup files.
