Transferring a site with a hosting plan

I redesigned a site for a client which has a CMS hosting plan. However, I’m not actually using any of the CMS features in the site.

We’ve connected it to the domain, published it and all that kind of thing. Site is live here: www.designforhealth.org

Now, we’re at the stage where I want to transfer the site to my client for them to manage and update on their side.

When I try to do that, I receive this message:

Is my only option to cancel the hosting plan (resulting in some site downtime), transfer to my client and have them repurchase the hosting plan?

Thanks for the advice

That’s what Webflow recommends.
