CIT will perform the migration in two phases. Phase I will be the migration to compatibility mode, and phase II will be the migration to production mode, which includes enabling-new-function mode and new-function mode. Compatibility modeAll catalog and directory table spaces are encoded in EBCDIC, allowing the Version 8 subsystem to coexist with Version 7 subsystems. This mode does not enable new Version 8 functions.Enabling-new-function modeCatalog and directory table spaces are in either EBCDIC or Unicode UTF-8. Some table spaces remain in EBCDIC because they have not yet been converted to Unicode. This mode is the transitional period between encoding schemes. A DB2 subsystem that is in this mode cannot coexist with nor fall back to Version 7. This mode supports only a limited set of Version 8 functions to support the enabling process.New-function modeThe following directory table spaces remain in EBCDIC in new-function mode:
All other catalog and directory table spaces are encoded in Unicode. A DB2 subsystem that is in this mode cannot coexist with nor fall back to Version 7. Additionally, a DB2 subsystem that is in this mode cannot coexist with nor return to Version 8 compatibility mode. New-function mode enables all new Version 8 functions. To disable Version 8 functionality, you can toggle between new-function mode and enabling-new-function mode, but you cannot backout the processing that originally occurred in enabling-new-function mode.
