CXX Upgrade › Downgrade a version 12 CXX to r11

Downgrade a version 12 CXX to r11

You can only downgrade a version 12 CXX to an r11 CXX when the CXX is not open.

To downgrade a version 12 CXX to an r11 CXX:

1. Backup the CXX using Version 12.
2. Initialize the CXX using r11.
3. Issue the Version 12 DBUTLTY CXXMAINT OPTION=CONVERT1211 to accept the Version 12 backup as input and build the r11 CXX with the definitions.

The Version 12 CXX database is downgraded to an r11 CXX database.

Note: The DBUTLTY CXXMAINT OPTION=CONVERT1211 command must follow an INIT AREA=CXX function as a following step. This command does not restore MUF DIAGOPTION CXX values used by r11 (08 or 32).
