Very good point

Good to see Lemmy compatibility!

Mastodon has groups similar to Lemmy communities, Threads could definitely implement them too.

Negative:

1. Ask the community if they would be okay to move. If there is a big backlash, just stay there.
2. Open the new community on the new instance, add the sidebar, the banner, everything to make it look like the previous one.
3. Post the the old community a link to the new community. Lock the old community.
4. Add a few posts to the new community to make the transition smoother

Hello,

I migrated a few communities in the past. Usually, it’s okay, except if you really have a lot of valuable content, it happens quite smoothly.

If people ask, it was from !dundermifflin@lemmy.ml to !dundermifflin@lemm.ee
