I may upgrade from a free .wordpress.com blog to premium soon. Assumedly that will take off the .wordpress part of the URL. But followers may not know that, unless they see a post I’m going to do announcing it. But what if they miss the announcement and try to go to the old .wordpress.com blog?
How do I not lose followers when I upgrade?
[WordPress.com](https://WordPress.com) has excellent chat support. They will walk you through the process of redirecting your old domain to your new domain. When someone goes to the old domain they will automagically be redirected to the new domain.
