I need to move my blog say example.blogspot.com to example.com and custom service provider say Hostgator. I want to do this migration without impacting the SEO.

What I am thinking of 1. Using the link below I just change pointing of example.blogspot.com to example.com. https://www.shoutmeloud.com/setup-blogspot-custom-domain.html

  1. After a week when all my pages are migrated from example.blogspot.com to example.com, I will revert the settings of cname and now exmaple.com starts pointing to HostGator

Is this approach ok or a better solution is there?
