Details

The following is the Support Statement for mixed Oracle RDBMS Version Support with Data Guard Redo Transport Services. 


Mixed Version Support means Combinations of any Version, Major Release or Patchset.  For Example:

  • 10.1.0.2 to 10.1.0.3 or higher
  • 10.1.0.3 to 10.2.0.2 or higher
  • 10.2.0.2 to 10.2.0.4 or higher
  • 10.2.0.4 to 11.1.0.6 or higher
  • 11.1.0.6 to 11.1.0.7 or higher
  • 11.1.0.7 to 11.2.0.1 or higher
  • 11.2.0.1 to 11.2.0.2 or higher
  • etc
  • through current 19c version

  • GoldenGate and Streams DownStream Capture
    • Mixed Version Support to a GoldenGate or Streams Downstream Capture Target Database is supported over an extended Time Period.
      • The COMPATIBLE Parameter of the Target Database must be equal to or greater than the Source Database COMPATIBLE Setting.
  • Logical Standby
    • Mixed Version Support to a Data Guard Logical Standby for Rolling Upgrade is supported (starting from 10.1.0.3) over an extended Time Period.
      • The COMPATIBLE Initialization Parameter of the Primary database must be at the version of the Oracle software being upgraded and the Logical Standby database's COMPATIBLE setting must either match that of the Primary Database or be higher.
  • Physical Standby
    • Mixed Version Support between a Primary database and a Data Guard Physical Standby is NOT supported at all until Oracle Database 11.2.0.1.  From Oracle Database 11.2.0.1 it is possible to configure the Physical Standby database with at a higher patchset or major release Primary database for purposes of a migration to new hardware provided that after a switchover to that standby, the database is not allowed to open and is immediately upgraded in the normal manner. 
    • In addition, starting with Oracle Database 11.2.0.1 a Physical Standby database can run at a higher PSE, CPU or PSU for the purposes of Standby First Patching.  See the note below for more information.

      Note: Starting with 11.2.0.1 it is possible to have a Physical Standby at a higher Patchlevel (Patch, CPU, PSU, BP) when the README of the Patch states that it is valid for Standby First Patching. Please see "Oracle Patch Assurance - Data Guard Standby-First Patch Apply (Doc ID 1265700.1)" for more information.

Note that in the supported Cases, the Primary/Source Database is at a lower version, and the Standby/Target Database is at a higher Version.
