@internic I'm also considering splitting my #Mastodon presence across 2-3 instances. Most of my follows are on lists, so ideally I'd find a tool to "migrate everyone except the ones on these three lists."
I think I'll just move everything onto my new "home" instance (#qoto, probably) and manually refollow my favorites on the old instance.
I'm unclear about the effect of putting a #redirect on the old instance, as we're advised to do--will that hamper my ability to continue having a distinct presence there?
