Upgrading Jenkins

In order to ensure the latest features, security, and compatibility are maintained, we need to update and upgrade our Jenkins installations. In this hands-on lab, we will have the opportunity to upgrade a Jenkins server to the latest available version. We will then ensure all the related tasks, such as data storage and possibly plugin updates, are completed.
