Methods and systems are provided for migrating a data integration facility, such as an ETL job, from a source data integration platform to a target data integration platform. Certain embodiments involve externalizing a metadata representation of a source data integration job; parsing the metadata representation; importing the parsed metadata into a plurality of object representations of the source data integration job; generating an intermediate representation of the source data integration platform based on the plurality of object representations; and translating the intermediate representation to generate a target data integration job; wherein the target data integration job is adapted perform substantially the same functions as the source data integration job.
