Beat way to migrate a community post history?

[jet@hackertalks.com]

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?

You can write a script for this:

# loop through all post
GET https://lemm.ee/api/v3/post/list?limit=50&sort=New&community_name=fedigrow&page=*page*
# take `post.ap_id` for each item
# then fetch it over activitypub on the other instance
GET https://lemmy.ml/api/v3/resolve_object?q=*urlencode post.ap_id*
# same thing for comments
GET https://lemm.ee/api/v3/comment/list?limit=50&sort=New&community_name=fedigrow&page=*page*
# again fetch
GET https://lemmy.ml/api/v3/resolve_object?q=*urlencode comment.ap_id*
