Cross-Platform Database Migration (across same endian) using RMAN Transportable Database (Doc ID 1401921.1)

Last updated on MARCH 09, 2021

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.4 and later
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Information in this document applies to any platform.

Purpose

+ We can use RMAN "Transportable Database" conversion for performing cross platform database migration between two operating system platforms belonging to the same endian format.

Use V$TRANSPORTABLE_PLATFORM view to check the endianess of source and target database platforms.

+ If you need to migrate database across endian platforms i.e. from a little-endian platform to big-endian platform or vice-versa, we cannot use RMAN "Transportable Database" conversion. In this case, you would be using transportable tablespaces along with RMAN datafile conversion.

+ Also, note that for certain platform migration, we need not use RMAN convert (either using "Transportable Database" or "Transportable Tablespaces") at all. For these platforms, you can directly perform RMAN duplication (active or backup-based) or RMAN restore/recover without any conversion:
