Seems like the downvote debate got another round on https://lemmy.zip/post/47242086/21088009 , so this could be useful

When I get some freetime I might set it up. My thought is if I can somehow move the community that's easy, but then for federation could I just "swap" it out to piefed and nobody would know? After all everything we do here is based on DNS, if DNS points to a new place, well who would know?

There is a feature to migrate a community from Lemmy to Piefed. There are a few limitations, but it's not too bad overall

"Swapping" it without using that feature might break federation as it relies on asymmetric keys to sign activities

ah damn, the keys would definitely break then, thanks for warning me about that - it's not worth the effort then for now. I was hoping if I just changed DNS that a downstream federated service would just see the update and start accepting new items.

Happy to help. Feel free to subscribe to !piefed_meta@piefed.social or !piefed_help@piefed.social in the meantime, things are moving quite fast

So my instance used to run Lemmy, I changed it all over to PieFed but kept the domain the same and recreated all the communities again. None of the content moved over - I was running out of HDD and needed to wipe anyway, other instances already had the old stuff cached so it looked the same on their end.

The only real headache I ever found was that PieFed doesn't (might be fixed?) support capitals in community names, so once recreated with a lowercase name those communities had a different ID on other Lemmy instances and would no longer federate. Oh and your subscriber numbers will forever look low, but the subbed people will stay subbed on their ends you just wont see it in the number.

Thanks that's essentially exactly what I was thinking of doing! Thanks for writing it all up. I'll take these and think on it
