The transportable tablespace feature enables you to move a set of tablespaces from one Oracle database to another.
You cannot export transportable tablespaces and then import them into a database at a lower release level. The target database must be at the same or later release level as the source database.
To move or copy a set of tablespaces, you must make the tablespaces read-only, manually copy the data files of these tablespaces to the target database, and use Export and Import to move the database information (metadata) stored in the data dictionary over to the target database. The transport of the data files can be done using any facility for copying flat binary files, such as the operating system copying facility, binary-mode FTP, or publishing on CD-ROMs.
After copying the data files and exporting the metadata, you can optionally put the tablespaces in read/write mode.
Export and Import provide the following parameters to enable movement of transportable tablespace metadata.
