Differential Upgrade utility

The Service Manager Differential Upgrade utility enables a developer to compare the specified files of two Service Manager systems to create a single unload file. The resulting unload file contains all the necessary records to make the files identical between the two systems.

The Differential Upgrade utility simplifies the way you move changes from a development environment into a test or production environment. You can also use this utility to move files between any two systems, such as:

  • Development and test
  • Unit testing and acceptance testing
  • Two different development systems

Important: We recommend that you understand how to export files and create different types of unload files before you use the Differential Upgrade utility.

The Differential Upgrade utility, just like the upgrade utility that upgrades applications from one version to another, relies on patch records and signatures. For more information on how to use the Differential Upgrade utility, see the Service Manager online Help topics under "Application Development - Differential Upgrade utility."
