@jafarm44 If you are upgrading the database from PostgreSQL 11 to PostgreSQL 12 in a Pega 8.6 environment, you typically do not need to run any Pega-specific upgrade scripts. Pega Platform is mostly database-agnostic as long as the schema structure and metadata are not changed. However, before upgrading, make sure PostgreSQL 12 is a supported version for Pega 8.6 by checking the Pega Platform Support Guide. Also, take a full backup of your database and application. After the upgrade, thoroughly test your application to ensure there are no compatibility issues. It’s also a good practice to revalidate and save rules and run the Database Class Mapping tool to confirm everything works as expected. Thanks
