Maybe part of the approach here could be to offer Hive as a sort of benefit to your existing patrons... instead of phrasing it as "a move" phrase it as a new "benefit" that offers patrons an opportunity to earn crypto as part of supporting you on Hive.

I see you have five different tiers on Patreon, so depending on which tier, someone coming over to Hive might get a Hive account loaded with anywhere (just shooting numbers randomly, here) from 50 to 1000 HP delegation for as long as they stay active.

You'd likely need a "How to Follow and Help us on Hive!" guidebook post either pinned or regularly recycled on your Patreon post feed... and it has to carve everything out in cardboard, almost like a Wiki of sorts.

I say that, not really having researched Patreon's policy on talking about off-Patreon venues...

I'm just brainstorming with you here, as someone who has noodled the same questions, both for my art, as well as for my wife's nonprofit.
