A method for migrating a legacy translation map to an evolved translation map includes determining an input file structure from input file structure information in the legacy translation map, determining an output file structure from output file structure information in the legacy translation map, and creating an XML binding object representation of source code for the input and output file structure. The method may further include creating an evolved language object representation of translation instructions in the legacy translation map, adding temporary segments to the XML binding object representation for the input file structure, and generating evolved language object representation of instructions to write input data into the temporary segments. The evolved language object representation of translation instructions is then merged into the XML binding object representation. The evolved translation map is then generated as an XML file based on the XML binding object representation resulting from the merging.
