I am wondering whether it is possible to upgrade a Jenkins 1.486 installation (on Ubuntu 12.04, official repository) to the latest version offered on jenkins-ci.org. I really need to upgrade because of some bugs but I do not dare to install the new version via "apt-get dist-upgrade" or "dpkg -i....".
Upgrading the whole system to Ubuntu 14.xx is not an option, because a) the server has no internet connection (local apt-mirror) and b) jenkins was removed from the ubuntu repositories in 2014. :(
I would just give it a try but the server is production system. It should not fail. ;) Has anyone had any experience with this upgrade?
Thank you very much!!!!
