Redirect FROM weebly to WP

Hello there,

I’m wondering if anyone knows the answer to my question. I’ve been searching the Weebly forum, and they don’t seem to want to give me information on how to stop using Weebly, understandably.

I have a potential new client that is currently on Weebly. I am suggesting a new domain name and to use WP as the CMS. They’re hesitant, as they fear people have bookmarked links. In normal circumstances these fears could be abated with redirects, but this site is one where it’s : theirbusinessname.weebly.com, so I don’t know if they can set up redirects from the subdomain. Does anyone know the answer to this question?

Thank you,
Amanda
