I'm in the process of replacing my old sitemaps with a new form which should better represent our site. However, as bots can take days or even weeks to scan all of our urls after submitted I do not want to adversely affect our site. If I submit the new sitemaps simultaneously so there are duplicates of all urls, will this affect my site negatively? The old sitemaps would be removed after the new ones are scanned.
Is this the correct process for replacing sitemaps, or does anyone have a different recommendation?
