Update jenkins war on one machine and then move it to another one: possible?

Question

I have a machine with blocked outgoing connections so it is not possible to update jenkins nor install the plugins I need for my work.

My idea is the following: I download the jenkins .war on my personal laptop and complete the installation + the plugin download. Then I just move this .war to the machine where I need jenkins to be up and running.

Is it possible? Where are the plugins/updated data stored? Also, would it be a problem the fact that my laptop has windows as os, while the destination machine is a linux RHEL?

Your solution sounds crazy :D

This could be help you:

Update Jenkins war

If you have shell access with root privilege, there is a manual way.

• Download latest war file inside your linux, using wget , curl or just upload it using winscp from your windows.
• Stop jenkins
• Backup EVERYTHING: linux snapshot, jenkins workspace, jenkins war file, etc
• Replace the old war with new war
• Start jenkins
