Prior to Geneva, Change Request installed the Conflict Detection, Best Practice Change Risk Calculator, Change Risk Assessment, and Bulk CI Changes plugins by default.

For new instances from Geneva onwards, the Standard change catalog, State Model, and Mass updates CI plugins are also installed by default.

If you are upgrading from a release prior to Geneva, you can choose to activate Change Management core, State Model, Standard change catalog, and Mass updates CI plugins. The State Model, and Standard change catalog plugins are dependent on the Change Management core plugin. Hence, activating either the State model or the Standard change catalog plugins results in the activation of the Change Management core plugin.

Also consider the following consequences of activating Change Management core and the subsequent changes you might need to make to best suit your organization's requirements:

• The previous change types are updated from routine, comprehensive, and emergency to standard, normal, and emergency respectively. Analyze customizations that you may have performed that reference old change type values since they are affected and require updating.
  Note: When Change management core is activated, the change types are updated.
