The apparatus may include machine readable memory configured to store technical data element identifiers (“TDEIs”) and a computer configured to receive a query for data lineage information corresponding to a first TDEI. The apparatus may include a processor configured to identify a level of commonality between the first TDEI and a second TDEI and determine whether the first TDEI and the second TDEI share a threshold level of commonality. Following a determination that the first TDEI and the second TDEI share a threshold level of commonality, the processor may identify any mismatches between the first TDEI and the second TDEI and determine whether a threshold number of mismatches exists between the first TDEI and the second TDEI. The processor may then transform the data lineage using ML. ## Claims ### Claim 1 Apparatus for leveraging machine learning (“ML”) to selectively update stored code with updated code, the apparatus comprising: machine readable memory configured to store a plurality of technical data element identifiers (“TDEIs”);
