Transfer Wix Editor Premium Plan to New Studio Site

I understand that the Wix Editor (not Editor X) sites can not be transferred to a Studio Site. I totally understand the reasoning. My question is, if I rebuild the Editor site in Studio. and get all of the site completed in the Studio Editor. Can I then transfer my Editor Premium Plan to a Studio Plan and assign the plan to the new site in Studio?
From what my understanding is, that cannot be done either?

I am just not clear, on if you can transfer and upgrade the “plan” and assign it to the newly built site in Studio, will the CMS, Contacts, Products, Subscriptions etc transfer to the new Studio plan.
This link makes it sound like it is possible as long as you build the site in Studio first…

Thank you in advance…

yes its possible. Just build your new site in Studio. Once completed transfer your premium plan accross from the old site (you will need to pay for any differences in plan costs)

Okay so I won’t lose my contacts and everyone that has signed up as a subscription? Because I book all my appointments through my current editor site.

you lose everything.
some items can be exported and imported back in.
