As far as I can tell Ontraport isn’t an LMS. Some of the features you might want are probably available via a WordPress install with the proper additional plugins.

You can’t just import a Wix website into WordPress itself. A clever designer could duplicate the Wix look and feel with the resources there.

You might look at using sub-domains of your Wix site’s domain to work within a WordPress feature set to bring a blog, a LMS if you need it, A CRM, and a storefront/cart system back to integrate into your Wix site (if that’s possible).
