We are in the midst of migrating from HTTP to HTTPS. According to Google Support, we need to have separate properties in GSC for each protocol. I also read that Google recommends that each property has a separate sitemap:
What URLs should our sitemaps list if we have redirects (from HTTP to HTTPS or the reverse)?
List all HTTP URLs in your HTTP sitemap, and all HTTPS URLs in your HTTPS sitemap, regardless of redirects when the user visits the page. Having pages listed in your sitemap regardless of redirects will help search engines discover the new URLs faster.
However, my company does not and will not have separate HTTP and HTTPS sitemaps. Does anyone know if this will cause issues and what those issues may be?
