SYMAPI database access is not forward compatible because a SYMAPI library cannot access a database that was created by a newer version of a SYMAPI application. If for example, the version of the local library becomes out of sync with the version of the local SYMAPI database (as a V8.0 SYMAPI library call from a SYMAPI client attempting to access a V10.3 database) it returns error: SYMAPI_C_DB_FILE_TOO_NEW. This restriction relates only to local databases. In client/server environments, accesses to a server database of a later version are automatically resolved by the SYMAPI, which performs all necessary translation of information between the client and the server.
