Creating a Pega 8 New Application Version – Application Versioning

Creating a Pega 8 New Application Version means you can edit application functionality in a new version of the application without changing the initial version.

Application versioning:

Pega provides two methods lock and roll and skimming for creating new versions of an application .

Lock and roll:

Lock and roll is best for incrementing patch versions. Small changes or patches are ideal for lock and roll.

In Dev Studio, navigate to the Configure > Application > Structure > RuleSet Stack page to access the Lock & Roll button.

Within lock and roll, you have three choices for updating the application rule:

  • Do not update my Application: when you update the patch version number of a ruleset without updating the application ruleset list
  • Update my Application to include the new Ruleset Versions: when you are rolling out an application and updating the minor version or when the application rule lists the ruleset patch version number.
  • Create a new version of my application: want to lock and roll the version and create a new application rule. You may enter a new application version, if different than the default one increment higher.

Skimming is better for minor and major versions. It is the process of saving the highest version of a rule into a new, higher ruleset version.

You must have the zipMoveSkim privilege to perform the skim

Two types of skims: minor and major

Minor Skim:

During a minor skim, rules are stored in a higher minor version.

Major Skim:

During a major skim, rules are stored in a higher major version.

Indicate whether the update is to be a major version (NN-01-01) or a minor version (NN-MM-01). Click Skim to begin the process.

Note: Skimming only copies the rules in the major version you select. For example, if you skim 02-ZZ-ZZ into 03-01-01, rules in version 01-ZZ-ZZ are ignored.
