Maps and structures from previous versions
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.
