I took the website creation prompt from Claude applied into Google workstation created the website made changes imported to GitHub then developed to vercel and now I have given the access of the website to globe just to check that is it searchable or not and the domain name is now .vercel.app and I have been in discussion with the client and he is most probably going to purchase a website. So my question is after selling, I have to just transfer the gate hub and the vercel only but to make the website searchable, only changing domain name would make it possible ? Or there any further steps please guide me what to do after the deal is cracked.
