How quickly will the new domain merge with the old one?

Question

Search Engine Optimization

There is a site with good traffic, 200 pages, the domain has been in the search engine index for more than 7 years. It's time to change the domain, and the current one expires in a month. The question arose: if I transfer the site to a new domain, and on the old one in htaccess I leave 200 redirects (one redirect for each page), then after what time the search engines (Yandex and Google) will glue the domains, or what they will do there, in general, they will officially transfer site to a new domain? Will he manage to transfer everything in a month, or is it a long procedure? I just would not want to get filters for copy-paste from the first domain on the second domain.

Answer 1

Small ones usually make it in a week

Answer 2

If you plan to move quickly and leave the domain to someone else, then this is a bad option. If there were links to the old domain, then you will lose them. The best option would be to make a page redirect, leave the old domain. Gluing domains for 200 pages can take 1-3 weeks on average. Do not forget to glue the duplicates on the new one via a redirect, including the https version, if one is planned.
