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

• Checking Character Set Compatibility
  To check character set compatibility, run these commands on both the source and destination databases.
• 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
  See how to determine if the tablespaces you want to use are self-contained, or have dependencies.
• 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.
• 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.
