Compatibility

Any map or structure created in any previous release of Talend Data Mapper can be executed in the current version of Talend Data Mapper. Older maps or structures may have been created using different metadata rules, but since all metadata is versioned, the current release of Talend Data Mapper will detect these differences and make the necessary adjustments. If you are using Talend Data Mapper to open an older map or structure, it may appear as unsaved when you open it (a star will appear in the editor's tab), this indicates the map or structure has been altered to bring it up to date with the current metadata format.

Care must be taken regarding map and structure compatibility between the designer and runtime since they may be different releases of Talend Data Mapper. It is possible to use a newer release of the designer than the runtime and therefore create a map that the runtime will not be able to process. If this happens, the runtime will give a clear error message indicating it could not open the map because of a version mismatch. At this point you will need to use a runtime of the same or later release than the designer that produced the map to execute the map.
