Hi @louisforan It's hard to say how much of an affect a site migration would have. SEO is a super complicated algorithm and I wouldn't be able to say how much or little of a hit your rankings would have. That said, if the url stays the same you could setup 301 redirects to help lessen the impact. Also, just to be clear, there isn't a way to "migrate" the site over to the Weebly platform. You would need to rebuild the site page by page. Does you site have a blog? I don't think there is a way to setup a 301 redirect for individual blog posts. If your site relies heavily on blog traffic I would definitely take that into consideration before moving.
