In accordance with an embodiment, described herein is a system and method for determining the migration success of an application (e.g., a batch application) from a second computing platform (e.g., a mainframe platform) to a first computing platform (e.g., an open platform). A first database associated with the first computing platform and a second database associated with the second computing platform can include the same data baseline. A set of triggers can be created on each database to capture database modification events generated by the execution of a job associated with the application on each computing platform, and to store the database modification events in a table in each database. The database modification events from each computing platform can be downloaded and compared to determine the success of the application migration.
