Verification of upgrade compatibility

Guidewire provides a command prompt build tool to use in determining if the source and target application configurations are sufficiently compatible to support the upgrade process. To use, run the following command from a command prompt on any cluster member.

system_tools -verifyconfig filepath

This tool compares the local server configuration with the configuration of the remote cluster. The filepath parameter defines the path to the local WAR/EAR file that contains the PolicyCenter application, pc.war, for example.

The tool provides an on-screen report that contains information about the feasibility of the upgrade changes for the server members in the cluster.

Source and target configurations are incompatible: If the source and target configurations are incompatible, Guidewire requires a full database upgrade. Guidewire does not permit a rolling upgrade using the target configuration. If a rolling upgrade of the cluster is not possible, the command lists the incompatible or missing files.
Source and target configurations are identical: If the source and target configurations are identical, no upgrade is necessary.
Source and target configurations are compatible: If the source and target configurations are compatible, Guidewire permits a rolling deployment of these changes.

Rolling upgrade in progress

If a rolling upgrade is in progress, there are several possible configurations active in the cluster. Running the -verifyconfig command option on a cluster member provides the following information about that cluster member:

The cluster member is running the source configuration.
The cluster member is running the target configuration.
The cluster member is actively upgrading itself.
