Compatibility Considerations for Transporting Data

When transporting data, Oracle Database computes the lowest compatibility level at which the target database must run.

You can transport a tablespace or a table from a source database to a target database having the same or higher compatibility setting using transportable tablespaces, even if the target database is on the same or a different platform. The data transport operation fails if the compatibility level of the source database is higher than the compatibility level of the target database.

The following table shows the minimum compatibility requirements of the source and target databases in various scenarios. The source and target database need not have the same compatibility setting.

Table 1-1 Minimum Compatibility Requirements

Transport Scenario Minimum Compatibility Setting
Source Database Target Database

Transporting a database using full transportable export/import

12.0 (COMPATIBLE initialization parameter setting for an Oracle Database 12c or later database

12 (VERSION Data Pump export parameter setting for an 11.2.0.3 or later database)

12.0 (COMPATIBLE initialization parameter setting)

Transporting a tablespace between databases on the same platform using transportable tablespaces

8.0 (COMPATIBLE initialization parameter setting)

8.0 (COMPATIBLE initialization parameter setting)

Transporting a tablespace with different database block size than the target database using transportable tablespaces

9.0 (COMPATIBLE initialization parameter setting)

9.0 (COMPATIBLE initialization parameter setting)

Transporting a tablespace between databases on different platforms using transportable tablespaces

10.0 (COMPATIBLE initialization parameter setting)

10.0 (COMPATIBLE initialization parameter setting)

Transporting tables between databases

11.2.0 (COMPATIBLE initialization parameter setting for an Oracle Database 12c or later database

11.2.0 (COMPATIBLE initialization parameter setting)

Note:

  • When you use full transportable export/import, the source database must be an Oracle Database 11g Release 2 (11.2.0.3) or later database, and the target database must be an Oracle Database 12c or later database.

  • When transporting a database from Oracle Database 11g Release 2 (11.2.0.3) or later database to Oracle Database 12c or later database, you must set the Data Pump export parameter VERSION to 12 or higher.

  • When transporting a database from an Oracle Database 19c database to an Oracle Database 19c database, you must set the initialization parameter COMPATIBLE to 19.0.0 or higher.
