If you did not run the Update Existing Application utility during the upgrade, you can run it after the upgrade to ensure that your existing applications take advantage of new functionality in Pega Platform. Run the utility first on your development system and test the changes. Then, run the utility again on the production system. The specific actions required for your application depend on your current version.
The utility lists the actions that will be performed, the number of records that will be modified, and an estimate of how long each action will take.
In the header of Dev Studio, click.
If any actions are listed, click Run to start the utility.
Test the application. If the test results are acceptable, repeat these steps on your production system.
