I have been given the unenviable task of mapping out a process for upgrading from Jenkins 1.642.4 to the latest LTS (currently 2.46.2). If I had to do this blind and unsupported, I'd start by creating a sandbox Jenkins with a clone of our existing jobs, plugin, and configuration, then drop the upgrade on it and see what exploded. We have a little over 100 plugins installed, so if I had to guess what's going to cause problems, I would expect it to be plugins which are broken by the upgrade, which then must be upgraded themselves, and before I know it I'm in dependency hell.
If anyone has experience with this, whether version-specific or just general tips on how to approach this, I'd love to hear them.
