advice on migrating a community?

I moderate a very polite community of about 1500 users. There are 2 other mods.

I'm not confident Reddit is the right place for it anymore. I just reached out to my fellow mods to see how they're feeling. We didn't participate in the blackout because

1. the most we've modded is marking something as a spoiler after someone posted and
2. I was reeling from IRL surprise badness (which seems mostly resolved)

Does anyone have advice on migrating a subreddit over to Lemmy?
