2. Use the RMAN convert command to convert data files to the target platform's endian format, if required.
3. Perform a full transportable export on the source database with the parameters
VERSI0N=12, TRANSPORTABLE=ALWAYS, and FULL=Y.
4. Transport the data files for all the user-defined tablespaces.
5. Transport the export dump file to the target database.
6. Perform an import on the target database by using the full, network_link, and transportable_datafiles
parameters.
7. Perform an import on the target database by using the full and transportable_datafiles parameters.
Identify the required steps in the correct order.
