System and method for determining the success of a cross-platform application migration

A method for determining the migration success of a batch application, comprising:

• providing a first computing platform, executing on a microprocessor, wherein the first computing platform includes an application container for executing an application migrated from a second computing platform;
• creating one or more database triggers and a modification events table in a first database associated with the first computing platform, and a second database associated with the second computing platform;
• receiving a job associated with the application at each computing platform for execution, wherein the job execution on each computing platform generates a plurality of database modification events;
• using the database triggers on each computing platform to capture the database modification events, and store them to the modification events table on that computing platform;
• and
• providing a client application comprising comparison logic;
• and
• determining a return code of the job execution on the first computing platform,
• generating an indicator indicating that the application migration is a failure if the return code does not indicate a successful execution of the job,
• comparing the database modification events from the first database and the database modification events from the second database if the return code indicates a successful execution of the job,
• generating an indicator indicating that the application migration is a failure if, based on the comparing, the database modification events from the first database and the database modification events from the second database do not contain the same set database operations, and
• generating an indicator indicating that the application migration is successful if, based on the comparing, the database modification events from the first database and the database modification events from the second database contain the same set database operations.

A non-transitory computer-readable storage medium storing a set of instructions for determining migration success of a batch application, said instructions, when executed by one or more processors, causing the one or more processors to perform steps comprising:

• providing a first computing platform, executing on a microprocessor, wherein the first computing platform includes an application container for executing an application migrated from a second computing platform;
• creating one or more database triggers and a modification events table in a first database associated with the first computing platform, and a second database associated with the second computing platform;
• receiving a job associated with the application at each computing platform for execution, wherein the job execution on each computing platform generates a plurality of database modification events;
• using the database triggers on each computing platform to capture the database modification events, and store them to the modification events table on that computing platform;
• and
• providing a client application comprising comparison logic;
• and
• determining a return code of the job execution on the first computing platform,
• generating an indicator indicating that the application migration is a failure if the return code does not indicate a successful execution of the job,
• comparing the database modification events from the first database and the database modification events from the second database if the return code indicates a successful execution of the job,
• generating an indicator indicating that the application migration is a failure if, based on the comparing, the database modification events from the first database and the database modification events from the second database do not contain the same set database operations, and
• generating an indicator indicating that the application migration is successful if, based on the comparing, the database modification events from the first database and the database modification events from the second database contain the same set database operations.
