Hey, @Scott Cummins - thanks for reaching out! It's a good question and one I had to inquire about myself.
So, my understanding is that an LOA is standard across the board.
Sounds like it might be a simple migration, but I'd ask that you reach out to your account manager to get the lay of the land.
If it's more complicated, it may require the number transfer crew, but I think this is a good place to start.
If you run into any hurdles or need extra help, please reach out here or shoot us an email at Community.Support@RingCentral.com.
