Use the transportable tablespaces feature to copy a set of tablespaces from one Oracle Database to another.

• Checking Character Set Compatibility
  Run these commands on the source and destination databases to find character sets that are compatible.
• Transporting Tablespaces Between Databases
  You can transport a tablespace or a set of tablespaces between databases.
• Task 1: Pick a Self-Contained Set of Tablespaces
  There may be logical or physical dependencies between the database objects in the transportable set and the database objects outside of the transportable set. You can only transport a tablespace set that is self-contained, that is, none of the database objects inside a tablespace set are dependent on any of the database objects outside of that tablespace set.
• Task 2: Generate a Transportable Tablespace Set
  After ensuring that you have a self-contained set of tablespaces that you want to transport, generate a transportable tablespace set.
• Task 3: Transport the Export Dump File
  Transport the dump file to the directory pointed to by the DATA_PUMP_DIR directory object, or to any other directory of your choosing. The new location must be accessible to the target database.
• Task 4: Transport the Tablespace Set
  Transport the data files of the tablespaces to a directory that is accessible to the target database.
• Task 5: (Optional) Restore Tablespaces to Read/Write Mode
  Make the transported tablespaces read/write again at the source database.
• Task 6: Import the Tablespace Set
  To complete the transportable tablespaces operation, import the tablespace set.
• Postmigration Tasks
  Complete these tasks to prepare the target Oracle Database for use.
