Explanation
There are several techniques for migrating data to a Database Machine. Migration can be done using Oracle Recovery Manager (RMAN) to backup from traditional storage and restore the data onto Exadata. Oracle Data Guard can also be used to facilitate a migration. This is done by first creating a standby database based on Exadata storage. The standby can be using Exadata storage and the production database can be on traditional storage. By executing a fast switchover, taking just seconds, you can transform the standby database into the production This provides a built-in safety net as you can undo the migration very gracefully if unforeseen issues arise. Transportable Tablespaces (B) and Data Pump may also be used to migrate to Exadata. Any technique used to move data between Oracle Databases can be used with
