Transfer site from Wix Editor to Editor X?

Please I will be glad if you reply. I don’t need a phone or video call with you. I just want you to say the method if it is possible to switch to Editor X, and say “No” if it’s not possible to switch. So I can give my client an answer. (We can’t open a new website because my Client has more than 3000 customers and they are subscribers of the website. If there is a way to migrate data and this will not damage any customer, you can tell me the way. If necessary, we can open a new website. But as far as I can see, only domain transfer can be done.)
