I want to switch our Jenkins to server to a better machine. The new Jenkins is installed and configured, but without the jobs. I planned to use Jenkins job import plugin in order to import all the jobs, but I have a small problem. My old jenkins installation requires login in order to see the config.xml, even though the anonymous user has read permission on the jobs. Currently I get HTTP error 403 on the old jenkins, and a NullPointerException in the Job Import plugin.
How can I move all the Jobs? I have about 50 jobs, so setting them one by one is saved as the last resort.
