A transitional mode of operation in the version-to-version migration process, during which the DB2 subsystem or data sharing group prepares to use the new functions of the new version. When operating in enabling-new-function mode, a DB2 data sharing group cannot coexist with members that operate at the prior version level. In enabling-new-function mode, fallback to a prior version is not supported, and new functions of the new version are not available for use. See also enabling-new-function mode*, compatibility mode, compatibility mode*.
