Question

Search Engine Optimization

registered in robots host - https and filamap - also indicated with https .
Now the question is - do you still need to load into the admin panel of Yandex and Google - this file, it already exists, but with http

Answer 1

Yes, of course, the URLs have changed! We need to communicate this through sitemap.xml. In this case, it is worth regenerating it.
And don't forget to add a new site to GSC(WMT) with https:// (pay attention to the www or non-www version you use and add that one) in order to collect statistics.

Answer 2

In accordance with the sitemap standard, the file must contain the addresses of the site where it is located. Therefore, yes, it is worth creating files with https addresses and specifying them in robots.txt.
