Oracle Cross-Platform Migration Guide
In Oracle database, you can achieve cross-platform data migration and upgrade by using the following methods:
- Using the Oracle Data Pump tool allows for importing and exporting database objects and data provided by Oracle. You can use Data Pump to export data from one platform to another and then import it on the new platform, making it suitable for small databases with a not large amount of data.
- Using Oracle GoldenGate allows for cross-platform data migration and real-time data synchronization. By configuring GoldenGate for data replication, it is possible to migrate data from one platform to another without downtime, while also achieving real-time data synchronization.
- Utilize Oracle’s Transportable Tablespace feature: Oracle offers a Transportable Tablespace feature that allows you to move data files and metadata between different platforms, enabling cross-platform data migration. You can convert a tablespace to a transportable format on the source database, then copy the transport files to the target database and restore the tablespace on the target database.
- Utilize Oracle RMAN for backup and recovery: You have the option to backup your database using Oracle RMAN, recreate the database on the target platform, and restore the backup data. This method is suitable for large databases with significant data volumes.
In general, choose the appropriate method for cross-platform data migration and upgrade based on specific circumstances, and remember to backup data during the process to prevent data loss.
