Using backupsets for Transportable Tablespaces reduces the volume of data you need to ship to the destination database. See how that works:
RMAN TTS on the source database
The tablespace is made READ ONLY before the new BACKUP FOR TRANSPORT command is done. At this point, you can also convert the platform and the endian format if required. Then on the destination site:
RMAN TTS on the destination database
The FOREIGN keyword indicates that this doesn’t use a backup taken at the destination. Practical example:

Hi Hesse,
Thank you for your post.
Does this work on 11.2.0.4?
Regards,
Navakanth
#2 von Uwe Hesse am November 1, 2015 - 09:59
Navakanth, you can use Transportable Tablespaces since version 8, but doing that with RMAN backupsets is a 12c New Feature
#3 von Howie am November 17, 2015 - 17:07
Hi Hesse,
My source database is 11.2.0.3 on AIX. My target database is 12C on Oracle Linux 6. Can I use this method to migrate the database between different Endian formats?
#4 von Uwe Hesse am November 23, 2015 - 09:56
Howie, no you can’t since it is a 12c New Feature. But you could use Transportable Tablespaces without backupsets to do that. See here for a verbose explanation: http://docs.oracle.com/cd/E11882_01/server.112/e25494/tspaces.htm#ADMIN11394

Thanks for the post. Very helpful
#6 von Naresh am Dezember 22, 2018 - 12:02
Hi Uwe, Can i use this approach for copy table (which is lie on single tbs) to another db (with same platform)
#7 von ashu am April 2, 2019 - 17:09
but can we change the directory for the dmp file ?As i can see .dmp is getting generated in $ORACLE_HOME/dbs as well
