We upgraded the Jenkins version in our windows system from 1.596 to 1.651.3.
Target is to upgrade to the latest version.
Couldn’t see the build history after upgrading using the war file. Is this being a known bug? Or do we have any fix for this? Is it safe to proceed the upgrade to the latest version. Please advise.
1.651 is over 8 years old. I don’t know if anyone is able to help you.
Especially with the major version switch from 1.x to 2.x there are many changes that you might need to consider.
Most important take a backup before trying anything out.
Or create a test landscape that has the same plugins and some test jobs for the scenarios you’re running.
