Following the Jenkins wiki, you’ll have to:
- Install a fresh Jenkins instance on the new server
- Be sure the old and the new Jenkins instances are stopped
- Archive all the content of the JENKINS_HOME of the old Jenkins instance
- Extract the archive into the new JENKINS_HOME directory
- Do not forget to change the owner of the new Jenkins files :
chown -R jenkins:jenkins $JENKINS_HOME - Launch the new Jenkins instance
- Do not forget to change documentation/links to your new instance of Jenkins 🙂
JENKINS_HOME is by default located in ~/.jenkins on a Linux installation, yet to exactly find where it is located, go on the http://your_jenkins_url/configure page and check the value of the first parameter: Home directory; this is the JENKINS_HOME.
