Goal

Starting with Oracle Database 10g, you can transport tablespaces across platforms. In this note there is a step by step guide about how to do it  with ASM datafiles and with OS filesystem datafiles.

If your goal is to migrate a database to different endian platform, the following high-level steps describe how to migrate a database to a new platform using transportable tablespace:

1.- Create a new, empty database on the destination platform.
2.- Import objects required for transport operations from the source database into the destination database.
3.- Export transportable metadata for all user tablespaces from the source database.
4.- Transfer data files for user tablespaces to the destination system.
5.- Use RMAN to convert the data files to the endian format of the destination system.
6.- Import transportable metadata for all user tablespaces into the destination database.

You could also convert the datafiles at source platform and once converted transfer them to destination platform.

The MAA technical brief "Platform Migration Using Transportable Tablespace" is available at

From 11.2.0.4, 12C and further, if converting to Linux x86-64 consider to follow this doc:
