I am tracking a website which is available under two domains (with and without a www. prefix). Currently the longer one redirects to the shorter one.However, it seems that the longer one was used when creating the account, and things like in-page analytics fail with an error:Error: The Website in your settings (http://www.example.com),  redirects into a different domain. (http://example.com). In-Page  Analytics currently works on only one domain. Note that  www.example.com and example.com are NOT considered to be on the same  domain. Also, make sure you're not redirecting from http:// to  https:// or vice versa.So, I inferred I should probably update the URL inside the Analytics. I found that the URL is editable in at least two places:Property Settings tab on a property list page (the one which lists profiles)Profile Settings tab on a profile page (one where there are tabs like Assets, Users, Goals and so on)Questions: Which one should I change? What will happen to already harvested data, will they be preserved?
Change URL of a site in Google Analytics
google analytics;url
You should change at both places. The property rules over all your profiles, but you will need to make sure the profiles match too. The harvested data will not change.
