Upgrade an r11 CXX to Version 12

You should only upgrade an r11 CXX to a version 12 CXX when the CXX is not open.

To upgrade an r11 CXX to a version 12 CXX:

1. Backup the CXX using r11.
2. Initialize the CXX using Version 12.
3. Issue the DBUTLTY CXXMAINT OPTION=CONVERT1112 command to accept the r11 backup as input and build the Version 12 CXX with the definitions.

The r11 CXX is upgraded to Version 12 CXX.

Note: The DBUTLTY CXXMAINT OPTION=CONVERT1112 command sets the CXX level to LEVEL 1 and each database format to FORMAT 1. The command must follow a DBUTLTY INIT AREA=CXX function in the same step or a following step. The r11 MUF diagnostic options, DIAGOPTION CXX, are not preserved in an r11 CXX backup and are not pushed into Version 12.
