I love Bravenet Pro. I have been using it for a couple of years now, and I design sites for other people so I always recommend Bravenet.
You won't necessarily have to "transfer" your site, but I would recommend it.
If you need help with any issues, contact me on Yahoo nightmare1158 and I will help all I can, I do know a bit about the workings of the site, although I am not anything but a user here.
