Hi,
While not a newbie to Jenkins, I am certainly a newbie to Jenkins
admin and I've been handed the task of upgrading our Jenkins server
from its current version of *1.564* to the latest, which, as of today,
is *1.636*.
Now, when someone else here attempted this some time ago, they had
issues (the details of which I don't currently have) but, suffice it
to say that they felt the need to roll back to our current version. I
believe they tried to jump to a version multiple versions up (possibly
to 1.600) but not the latest at the time. So, I am looking for advise
as to the best approach to this.
I don't want to have to upgrade a version at a time (84 upgrades) so,
besides perhaps using the 'major enhancement' marker in the
*Changelog* <https://jenkins-ci.org/changelog>, what would be the
recommended intermediate versions to which I should upgrade?
*Any other words of advice?*
1) backup your JENKINS_HOME (accidents happen)
2) don't go to 1.636 unless you have to - use an LTS
<https://wiki.jenkins-ci.org/display/JENKINS/LTS+Release+Line>if you
want stability which it appears you do as you have not upgraded in a
long time!
3) make sure any JNLP slaves have their slave.jar updated
