How to switch from LTS to Weekly release for Jenkins in Windows?

Currently have a Jenkins stable/LTS instance running on Windows Server 2008 R2 which I would like to switch to weekly release. Is there anyway I could edit some config files to have it switch from LTS to Weekly release without a complete reinstallation?

Solution 1:

Found the quick way of doing this:

Go to Manage Jenkins -> Manage Plugins -> Advanced tab.

Change the update Site URL to https://updates.jenkins.io/current/update-center.json (note the "current" part in URL).

Now go back to Updates -> Check Now and you should see a new version is available for download (obviously if newest in weekly is higher than the LTS release, which is almost always the case).

Switching back should be as easy as change the "current" to "stable" in URL, however you might need to wait until the LTS version number surpass the weekly version number.
