Rolling upgrade and business rules

During a rolling upgrade, Guidewire disables the ability to deploy a rule in a production environment. The intent is to prevent the deployment of a rule that contains data that is incompatible with the current environment, thereby causing the rule execution to fail.

During a rolling upgrade, PolicyCenter:

Disables the Deploy All and Deploy Selected options on the rule list screen.
Disables the Deploy button on the rule detail screen.
Displays an alert message on the rule list and rule details screen that indicates rule deployment is not possible due to an ongoing upgrade.

Thus, during a rolling upgrade, Guidewire hides the Deploy functionality.
