  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using. There may be specific guidelines or known issues that can provide further insight.
  Testing: Conduct tests with a smaller subset of data to identify if the issue persists. This can help isolate the problem and allow for easier troubleshooting.
