Ensure that your strategies are compatible with the optimized strategy execution engine that was introduced in Pega Platform™ 8.1 by running a post-upgrade utility that checks strategies within your application for areas that you can optimize.

For example, you can improve performance by reducing the number of page properties that are copied from one shape to another. Running the utility produces a report that you can use to plan the required updates to your strategies.

After upgrading your application, you can launch the utility from the Configure > System > Release > Upgrade > Upgrade Tools menu of Dev Studio, as shown in the following figure:

You can run the utility for all strategies within your application or analyze a single strategy, as shown in the following figure:

If you choose to analyze a single strategy, all its substrategies are also included in the analysis, to give you a complete picture. The utility flags components that you can optimize, as well as components that cannot be optimized, and legacy logic that will produce different results after optimization. For more information about the impact of optimization on legacy components, see Optimized strategy execution engine compatibility: known issues and fixes.

For more information about running the utility, see "Running the optimization check utility for decision strategies" in the Pega Customer Decision Hub Upgrade Guide on the Pega Customer Decision Hub product page.
