You can do it but the procedure is a bit weird.
The gaining registrant should go to netsol, then select 'domain transfer'.
Enter the domain(s), then press 'Get started'.
On then next screen, select 'Person requesting to transfer #######, which is currently registered with another Network Solutions Customer or Partner, to my account.'
Then skip through the screens (they have several promotional screens, it is very godaddy-like). Also they will automatically add 3 years renewal in your shopcart, remove this so your total order is $0.
Finally buyer should log in or create an account and voilÃ*.
