Say for more than half a decade (really its been a decade) Cathy has blogged as DomesticPsychology.com and she has. Let’s say on a whim she decides she would rather be blogging as CathyMcCaughan.com (in reality she hasn’t..this is simply a working example). Currently http://CathyMcCaughan.com forwards to http://domesticpsychology.com/. To complicate things, let’s say they are registered at 2 different registrars so DNS is handled by two different organizations.
Many options exist for moving a domain name. What is the best way to make http://cathymccaughan.com/ the primary url for Cathy’s website instead of http://domesticpsychology.com/ without losing the search engine rankings or readership and without creating broken links?
