Upgrading Paperless-ngx several revisions behind (lemmy.world)

Hey everyone. For a variety of reasons I’ve ended up with a paperless-ngx install that has not been upgraded for a while. It’s currently on 1.17.1, and I’ve been researching to figure out the best way to get back up to current. I’m worried about major changes that have happened over time and what the best way to go about this is, but I’ve not had good luck finding something that gives me the confidence to go about it. Hoping someone here has some guidance. Cheers!

I haven't gone through your specific case, but generally what I do when doing a major update with potentially breaking changes:

Read the upgrade guides, if they have them. Some devs will put them out if they know their users will encounter issues when upgrading. If they don't have an upgrade guide, there might be some in the change logs. Going from 1.17.1 to (assuming) 2.x.y, check the change logs at 2.0.0.
Backup everything. I'd recommend doing this on a regular basis anyway.
(If you're running it in a docker container) Setup a second instance, restore the backup, then run the upgrade. You'll be able to check to see if it breaks at all. If it works, you can just destroy the old one and use the new one
(if you're not running it in a container) with the backup, try upgrading. If it breaks, you should be able to uninstall & reinstall the old version, then restore the backup
