How can a site quickly change the domain in the search engine?

Hi all. I recently saw a person in the issuance who very quickly moved to a new domain. His site was banned literally August 8, the same day he bought a new domain and redirected from the old site to the new (probably included the move to the GSC, but I can not be sure). I also did not see what manipulation of the site he did before the redirect, but looked in Ahrefs saw that he restores its link profile. The site moved literally a day, though only on one request, for the other requests also hangs the old domain.

If anyone knows what the method or how you can speed up the move site, please share the information, I think that many will be interested. Thank you in advance!

I think it's a normal process there is no speed-up process if you have a new domain and you redirect from the old site it takes only a few hours maximum of half a day

So there is not a big deal to speed up redirection its a normal process
