Upgrade flag required for upgrade

To prevent the unexpected upgrade of a PolicyCenter server, Guidewire requires that you set a PolicyCenter upgrade flag before starting the upgrade process:

• To start a full upgrade, you must first click Start Full Upgrade in the Server Tools Upgrade and Versions screen on any cluster member. At the completion of the upgrade, PolicyCenter removes the flag automatically.
• To start a rolling upgrade, you must first click Start Rolling Upgrade in the Server Tools Upgrade and Versions screen on any cluster member. After completing the upgrade of all servers in the PolicyCenter cluster, you must click Rolling Upgrade Complete on the Upgrade and Versions screen to remove the upgrade flag
