Possible to move full article state between services?

I have been granted a new work laptop which is unfortunately far more restricted than in the past, so iCloud Drive is fully disabled and it does not seem like NNW supports a separate iCloud login flow (like app-passwords).

I know I can port my feeds via OPML, but is there a way to move things like Starr’d articles When I moved from Unread and Reeder back home to NNW when it came back on the scene, it was unfortunate to lose all my stars. So just wondering if there’s a way to maintain that if I were to move over to something like FreshRSS.

There isn’t a way that I know of to move article states between services. (Well, you could probably do it with some custom software, yes.)

Yeah I’ve never seen an export in any reader that saved stars, just didn’t know if I would be able to reassign the account for a feed and it just carry things through.

Would be great for portability if there was a solution, or if you could either merge/dedupe feeds across accounts or some kind of archive state so you can remove or unsubscribe without nuking favorites.

I guess maybe I’ll try to script out to a read later some how, but at that point I almost wish Star was just a replacement for that all along.
