Restore Of Jenkins Configuration

[Paul Wilkins]

Hello

I attempted to revert a Jenkins upgrade and this totally killed my Jenkins instance.   I have an old image pre upgrade of the Jenkins machine, all these machines are AWS Ec2 windows machines.   If on the failed machine I uninstall Jenkins and re install version 1.555 which was the pre upgrade version is it easier and quicker to manually re apply all of the jobs and configuration or is there a way of copying the xml files from the old image of this machine.

I don't want to just swap these machines out as the image is quite old and the actual set up of the machine is different.   But the set up of jenkins should be the same as this hasn't changed over time.

I really hope that makes sense.

Thanks

Paul.

Jenkins uses mostly XML file-based storage, so you should be able to copy over the entire JENKINS_HOME (typically /var/lib/jenkins) and use that.

Make sure you copy over other Jenkins-related files like /etc/default/jenkins or /etc/sysconfig/jenkins (depending on distro) as well, as they may contain important configuration.
