For 8.3 and earlier patch releases, the Pega zero-downtime, split-schema patch process scripts move rules into the rules schema patch, while the scripts move rules and objects in and out of the data schema using an in-place process.
For details about the difference between a major upgrade, a minor upgrade, and a patch, see Pega Platform patches.
Use the out-of-place patch process for zero-downtime patches
Complete your patch without downtime using the out-of-place patch process. Pega zero-downtime patchs are reversible.
While the out-of-place patch process is the recommended method, some clients might prefer to apply the patch in-place, which applies the patch without using the temporary data schema. In-place patchs involve down time. For details, see, Applying a patch in-place.
- Patching systems without downtime (Pega 8.3 and earlier)
The Pega patch process is zero-downtime for highly available systems when you use the out-of-place process so you can continue working in your application while you patch your system.
- For Pega Platform version 8.3 and earlier: Applying a patch in-place
Apply a patch in-place on systems that do not require minimal downtime.
- For Pega Platform 8.3 and earlier: Post-patch tasks
