Thanks for providing the details of your configuration and the steps that you tried. That makes it much easier for others to help you. The upgrade from 2.462.3 to 2.504.3 may be challenging in your environment because you’re using several plugins that are not available from the Jenkins update center and one of those plugins (simpleldap) is likely related to authentication. One or more of those private plugins may need to be upgraded to support Spring Security 6 and Java 17. ### Private plugins The plugins you’re using that are not available from the Jenkins update center are: - ErrorPublisher - buildlist - buildlistCli - javascript - multi-agent-config-plugin - perms - permslist - seccli - singleldap - agent-squatter You should evaluate if you can remove those plugins. If not, then you’ll need to review each of them to decide if they need to be updated for Spring Security 6 and Java 17. ### Deprecated private build of a plugin You have a private build of a deprecated plugin installed. It should be removed: - scp ### Deprecated plugins You have deprecated plugins that should be removed, including: - [JavaScript GUI Lib: ACE Editor bundle plugin](https://github.com/jenkins-infra/update-center2/pull/857) - [Multi-Branch Project Plugin (DEPRECATED)](https://plugins.jenkins.io/multi-branch-project-plugin) - [PMD Plug-in](https://github.com/jenkins-infra/helpdesk/issues/2089) - [Multijob plugin](https://plugins.jenkins.io/jenkins-multijob-plugin) - [Pipeline: Declarative Agent API](https://plugins.jenkins.io/pipeline-model-declarative-agent) - [Popper.js API Plugin](https://plugins.jenkins.io/popper-api) - [jQuery UI plugin](https://plugins.jenkins.io/jquery-ui) - [Static Analysis Utilities](https://github.com/jenkins-infra/helpdesk/issues/2089) - [JavaScript GUI Lib: jQuery bundles (jQuery and jQuery UI) plugin](https://plugins.jenkins.io/jquery-detached) - [Crowd 2 Integration](https://github.com/jenkins-infra/helpdesk/issues/3854) - [Bootstrap 4 API Plugin](https://plugins.jenkins.io/bootstrap4-api) - [Popper.js 2 API Plugin](https://plugins.jenkins.io/popper2-api) - [WMI Windows Agents Plugin](https://github.com/jenkinsci/windows-slaves-plugin?tab=readme-ov-file#notice-of-deprecation) - [Checkstyle Plug-in](https://github.com/jenkins-infra/helpdesk/issues/2089) - [Code Coverage Plugin](https://plugins.jenkins.io/code-coverage-api) - [Extended Choice Parameter Plugin](https://github.com/jenkinsci/extended-choice-parameter-plugin?tab=readme-ov-file#end-of-life) - [Pipeline: Deprecated Groovy Libraries](https://plugins.jenkins.io/workflow-cps-global-lib) - [Cobertura Plugin](https://plugins.jenkins.io/cobertura) - [Multiple SCMs plugin](https://plugins.jenkins.io/multiple-scms) - [Translation Assistance plugin](https://github.com/jenkins-infra/update-center2/pull/719) - [Confluence Publisher](https://github.com/jenkins-infra/helpdesk/issues/3856) - [JavaScript GUI Lib: Moment.js bundle plugin](https://github.com/jenkins-infra/update-center2/pull/857) - [JavaScript GUI Lib: Handlebars bundle plugin](https://github.com/jenkins-infra/update-center2/pull/857) - [Icon Shim](https://plugins.jenkins.io/icon-shim) ### Upgrading to 2.479.3 When I applied those changes to your Jenkins 2.462.3 on Java 11, I was able to run Jenkins 2.479.3 with Java 17. It reported there are 191 plugins to upgrade. I upgraded those 191 plugins and restarted Jenkins successfully. ### Upgrading to 2.504.3 I then started Jenkins 2.504.3 and it reported 8 more plugins to upgrade. I upgraded those plugins and restarted Jenkins successfully. ### Unresolved security vulnerabilities After completing those steps, there are still 2 plugins with unresolved security vulnerabilities. You should evaluate those plugins to decide if you can remove them. The plugins with unresolved security vulnerabilities are: - [docker-build-step 2.12](https://plugins.jenkins.io/docker-build-step) - [CSRF vulnerability and missing permission check](https://www.jenkins.io/security/advisory/2024-03-06/#SECURITY-3200) (no fix available) No fixes for these issues are available. It is recommended that you review the security advisory and apply mitigations if possible, or uninstall this plugin. - [build-metrics 1.3](https://plugins.jenkins.io/build-metrics) - [Reflected XSS vulnerability](https://jenkins.io/security/advisory/2019-10-23/#SECURITY-1490) (no fix available) - [Stored XSS vulnerability](https://www.jenkins.io/security/advisory/2022-06-30/#SECURITY-1118) (no fix available) - [Missing permission checks](https://www.jenkins.io/security/advisory/2022-06-30/#SECURITY-2643) (no fix available) No fixes for these issues are available. It is recommended that you review the security advisory and apply mitigations if possible, or uninstall this plugin. ### Replace Blue Ocean with Pipeline Graph View In addition to those steps, you should consider removing the Blue Ocean plugins and replacing them with Pipeline Graph View. Blue Ocean is no longer being enhanced and the Pipeline Graph View plugin provides a very nice visualization of Jenkins Pipelines. You can read more about it in the [blog post](https://www.jenkins.io/blog/2025/05/02/pipeline-graph-view/) by Jan Faracik.
