This Document explains the new 12c feature:  Cross-Platform Data transport Using rman Backup Sets across different Endian Platform.

RMAN can transport databases, data files, and tablespaces across platforms using backup sets. Performing cross-platform data transport with backup sets enables you to use block compression to reduce the size of backups. This improves backup performance and reduces the time taken to transport backups over the network.

A cross-platform backup is an RMAN backup that can be restored on a destination platform that is different from the source platform


NOTE:  If the source and destination are running Oracle Database 19.18 or higher, see:
