Hi@MD,
You can move your Jenkins server to a different system. Just follow the below-given steps.
- 
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.
 
- 
Launch the new Jenkins instance.
 
- 
Do not forget to change documentation/links to your new instance of Jenkins.
 
- 
Do not forget to change the owner of the new Jenkins files.
 
 $ chown -R jenkins:jenkins $JENKINS_HOME.
