Welcome to the Q&A Forum

Hi Arun It's certainly best practice to move to a root directory. As you say visitors are then coming to one domain, not a subdomain. All you need to do is page by page redirect through a 301. When you say they are being 'redirected to 301 code' this is perfectly OK. The 301 code just tells Google that the page has moved permanently. It takes Google a short while to recognise the new pages as replacing the old ones and for that period you can see old and new in Google, causing a short period of duplication which could affect the rankings. You just need to sit it out - by all means, do a Fetch in Search Console to help speed up the process. Search Console>Crawl>Fetch as Google. Regards Nigel
