Patching systems without downtime (8.2 to 8.3.x)
Pega supports clients applying release 8.2.x and 8.3.x patches using a zero-time patch process to apply the latest cumulative bundle of bug and security fixes since the last minor release. For releases 8.2.x and 8.3.x, the Pega zero-downtime patch 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 software maintenance and extended support policy.
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, For 8.3 and earlier: Applying a patch in-place.

- For 8.3 and earlier: Applying a patch in-place
Apply a patch in-place on systems that do not require minimal downtime.
