Explanation:
This example example is a dumpfile-based full transportable export/import operation. In this case the metadata from the source database is exported to a dump file,and both the dump file and the tablespace data files are transferred to a new system. The steps would be as follows:
* (1) Set user tablespaces in the source database to READ ONLY.
* (3) Create a CDB on the destination system, including a PDB into which you will import the source database.
* (4) From the Oracle Database 11g Release 2 (11.2.0.3) environment, export the metadata and any data residing in administrative tablespaces from the source database using the FULL=Y and TRANSPORTABLE=ALWAYS parameters. Note that the VERSION=12 parameter is required only when exporting from an Oracle Database 11g Release 2 database.
* (5) Copy the tablespace data files from the source system to the destination system.
* (6) In the Oracle Database 12c environment, connect to the pre-created PDB and import the dump file.
