How to migrate a Jenkins instance from a 1.x server to a 2.x server?

[David Aldrich]

Hi

I discussed under a separate thread our difficulty in upgrading from Jenkins 1.656 to 2.3. After upgrading jenkins.war our server failed to start.

Stephen Connolly advised me:

It seems prudent for us to do a fresh install of Jenkins 2.6 under Tomcat.

How should we migrate the job / slave / people / plugin configurations from the old 1.x server to the new 2.x server?

Best regards

David

If you're not depending on tomcat's security, then just crawl the mailing list for "migration" and the likes. There's nothing specific really about 2.x for that.

And always, test it first on a test instance. And make sure your backup works before trying so.

Cheers
