Question

Do i have to re-submit a sitemap or what? Please help guys i want to change from index.php to the first option.

Answer 1

• Use proper 301 (permanent) redirection from the older URL to the newer URL using site's HtAccess file just after you change the URL of pages.
• Use Google Search Console's 'Fetch as Google' function to let Google know about the changes.
• Reconstruct the sitemap and RSS files and resubmit those to search engines' webmaster tools.
• Rework on the canonical tags of each webpage (modified URL pages)
• Change internal URLs accordingly (though redirection & canonical tags will do the job, still mixing of older and newer URL versions for the same link is not recommended)
