New Validate Platform Improvements and Functionality

Upgrade and Migration Improvements

Get up and running faster by starting the Validate Server, even if some projects fail to migrate. Successful migrations will be available immediately, and failed migrations will be automatically disabled. Save time by migrating individual projects without having to restart the Validate Server. Apply fixes and re-migrate problematic projects without interrupting the use of successfully migrated projects.

Project Migration Status

The Validate project list now indicates the current state of your project and provides actionable insights to resolve issues that may occur during upgrades and migration. Projects can be enabled/disabled to limit usage during upgrades, while projects that fail to migrate will no longer block Validate services from starting. Instead, project status will inform users that migration needs to be completed. Project status can also be checked using the kwadmin command or using the Web API to query the current project state.

Exclude Individual Projects from Migration

To help speed up migration, you can exclude specific projects. Excluded projects will not be migrated and will appear as disabled in the Validate tools. Later, you can migrate and enable excluded projects individually without restarting the Validate Server. For details, see Migrate your projects_root directory.

Prioritize Migration of Specific Projects

To prioritize important projects, you can assign a priority list which specifies the order in which projects will be migrated. Projects not included in the list will be migrated in the order of their project ID. To learn more, see Migrate your projects_root directory.

Import or Duplicate Existing Projects

You can now import a project from another Validate server, even if the project name matches an existing project on the target server. For more information, see Import your projects and server settings.

Improved Migration Logging

Migration logs are greatly improved to provide detailed information on the status of project migration steps and the logs are persisted to aid in troubleshooting if needed.

Download Issue List as CSV

The new CSV download button available at the top of the Issues page will download a list of defects based on the current search query in Validate. For additional issue information such as line number, comment, and justification, you require a subscription to the Validate Advanced Compliance Reporting package.

Expanded Search

Regular Expression (RegEx) search capabilities for Validate Modules provides increased support for the use of* and ** wildcard characters when specifying paths to your file system. See modules documentation for more information.

New Role Permission

Added change issue owner permission that provides the ability to allow users to change issue owner without being able to change issue status.

Preserve License Logs for Audit Purposes

You can now keep logs for auditing purposes, by appending the logs to your license server license.report.log file instead of overwriting the file after the server restarts. To learn about the append.license.logging setting, see kwservice or validate service.
