About this task
Liberty offers installation from a ZIP archive file or a self-extracting Java archive (JAR) file as an alternative to using IBM Installation Manager. If you installed Liberty using one of these archive files, you can upgrade the product license by applying an executable JAR file, available from IBM Fix Central or the Passport Advantage website.
- Upgrade an ILAN edition or other unsupported edition to a supported production edition.
- Upgrade a basic edition to a more advanced edition for access to advanced features.
License JAR file | Source edition | Target edition |
---|---|---|
wlp-core-license.jar | Unsupported ZIP or JAR file installations | WebSphere Application Server Liberty Core |
wlp-base-license.jar | Unsupported ZIP or JAR file installations | WebSphere Application Server Liberty |
WebSphere Application Server Liberty (ILAN) | ||
WebSphere Application Server Liberty Core | ||
wlp-nd-license.jar | Unsupported ZIP or JAR file installations | WebSphere Application Server Liberty Network Deployment |
WebSphere Application Server Liberty (ILAN) | ||
WebSphere Application Server Liberty Core | ||
WebSphere Application Server Liberty |
For example, an installation of WebSphere Application Server Liberty Core requires features from WebSphere Application Server Network Deployment Liberty. If you have the required entitlement, you can download the wlp-nd-license.jar license file and apply it to your Liberty installation, which upgrades the license from WebSphere Application Server Liberty Core to WebSphere Application Server Network Deployment Liberty. Upgrading the license does not install any features from WebSphere Application Server Network Deployment Liberty, but it enables you to install features for the edition to your Liberty installation if needed.
