An object of the present invention is to create a migration mapping definition based upon computer program changes and use the migration mapping definition to migrate instance data from an older software version format to a newer software version format. A developer uses edit commands, such as mouse commands and keyboard commands, to update a computer program. For example, a software developer may upgrade “Application XYZ” from version 1.0 to version 2.0 in order to include a simpler approach to import images, as well as the ability to import newer image format types. As a developer updates a computer program using edit commands, the edit commands are stored in a migration mapping definition. In turn, the migration mapping definition is deployed, along with the updated computer program, to an end user. The end user then uses the migration mapping definition to migrate instance data generated by the original computer program to instance data that is usable by the updated computer program.
