I have two lemm.ee communities and I very much want to keep the post history in one community for discover ability and archival purposes.

What tools and methods are available to transfer posts from one instance to another?

Update, so you can backfill, using

https://piefed.social/retrieve_remote_post

BUT if you want to backfill comments you need to use the comment url and not the post url

https://hackertalks.com/post/4924264/5510024 doesn't work
https://hackertalks.com/comment/5510024 works. great

This could benefit from automation, but all the difficult parts are there.

Credit goes to Blaze they really know lemmy inside and out.

Also - If you edit a old post, that does get picked up by piefed.social even if it doesn't have the original post. so a edit does cause refederation... this works for comments too
