The steps pertain to Oracle Database 11gr2 11.2.0.4 and later.


Goal

The steps provided in this document will assist with migration from an existing environment consisting of 11g non-CDB databases and 12c and later CDB databases to an Exadata cloud based environment in a manner providing limited downtime and easy fallback should issues arise during the migration. Included in the steps is the ability to optionally incorporate Oracle Transparent Data Encryption prior to the migration. The defined process is supported for 11.2.0.4 non-CDBs and 12.1.0.2 container databases (CDB) and later container databases.

This MOS document is in its first design phase (“Concept”) and we expect to continue to modify it during next phases (“Testing” and “Refinement”). Readers are encouraged to validate the code and samples in a Test environment first before applying them in production however this level of verification is being targeted before full release to customers.  This process has been internally tested directly on Oracle Cloud provisioned hardware and software.
