Moving a domain from one account to
another is called Splitting. From within your account, select on the "Domains"
tab from the blue menu bar. Select the option for "Domain Services". Please look
on the top right-hand side of the page and you will see a shaded box with the
title "Global Domain Settings". The second link in that box will say
"Split/Consolidate Domains". Please click this link.
Inside the
"Split/Consolidate Domains" page, you will see the "Create New Account" link on
the top of the page, at the very end of the text in the shaded box. Create your
new account first, and then return to the "Split/Consolidate Domains" section by
following the previous instructions, but this time, you will enter the username
for the other account, select the domain you would like to move, then confirm
your changes.
