Piefed has built-in processes to aid in moving communities to it. See the previous reply from Blaze.
Sadly it's not quite feature complete.
Yes, it will take an existing community and make a piefed community from it, but it wont import old posts, and it wont re-federate the old community content into the new community
lemmy-federate doesn't support piefed yet, so federating your new community may be troublesome
the main piefed.social instance has strong opinions on defederation that may limit community reach (in fact this is why lemmy-federate doesnt support piefed)
The piefed community migration feature does import old posts, but it doesn't refederate them, so they'll only be visible to local users
Only if those posts are already on the piefed instance at the time of migration.
For example if nobody was subscribed to the community or if the piefed instance is new then none of the backlog will be migrated.
There is a manual way to import posts one at a time, so that's a option.
I'm excited for the future of piefed. At this moment there are real tradeoffs community owners need to consider.
That's exactly how I did it when we spun up the new instance.
And once all the of the content was here, we transferred kicked off the transfer process.
It's not feature complete, as you said. In our case, it broke, because of a bug around the way it handled community names that use upper case letters, which required editing the database to fix
But despite that, at the end of it, we have the old content on the new community. Even if it doesn't federate, it's not lost
