Step 1: Create a new site in Google Webmaster tools and add your site map this way (submit the same thing I use for bing to google) only !
Step 2: Change your links everywhere.
I had to change in the following places
- Google Plus
go to http://hacktohell.disqus.com/admin/tools/migrate/ (here hacktohell is my unique id , use your unique id there) . Use the start Wizard button and follow it .
Step 4:Migrate Google Analytics i.e create a new Google Analytics account.
Step 5:Submit to bing and yahoo.
That's all enjoy your new domain !
