Pega Platform supports a split schema database architecture, which separates rules and data into separate schemas. This is essential for enabling minimal to zero downtime during Pega Platform application and strategic application upgrades or patch installation. During the upgrade, you can migrate the upgraded rules schema to the higher environment and do the data schema only upgrade. However, you will need to go through the same steps for upgrading the strategic apps as you did in the lower environment. Please note that you cannot run two versions of Pega Platform against the same PegaDATA schema at the same time. The newer version of Pega Platform might make changes to cases and data that are not forward compatible, resulting in the older Pega Platform version unable to process the updated cases and data.
