Coexistence and Migration

Coexistence and migration refers to the current customer environment containing various levels of tagged and non-tagged data, and different levels of application support. CDRA provides the following means by which the current environments can coexist, and at the same time allow for a reasonable migration to a more architected environment:

  • Wherever possible, the CDRA-defined Coded Character Set Identifier (CCSID) values are assigned to be the same as the corresponding code page identifiers.
  • CDRA has defined CCSIDs for many coded character sets that are currently in use but have not been identified as interoperable. These CCSIDs are called Coexistence and Migration CCSIDs.
  • CDRA provides many conversion tables that convert between the Coexistence and Migration CCSIDs and the Interoperable CCSIDs.
Existing Tagging Methods

Some existing architectures and implementations have provisions for tagging. Some of these recognize code page identifiers (CP) only, while others recognizecharacter set identifiers (CS) and code page identifiers (CP). These identification methods are considered intermediate forms of CDRA's long-form identification, which is composed of an encoding scheme, character set and code page pairs, and additional coding-related required information.
