This is from Patrick "P-mo" Moroney who thinks about these things day and night, even when is wife is talking to him. So there's a good chance he sacrificed the health of his young marriage just to come up with how you can transfer your domain names smoothly and without any interruption to your email or websites.
1. Purchase a transfer. And make sure to do the next 4 steps BEFORE clicking the link on the approval email that we will send to you, because you are unable to modify the nameservers once we fully submit the transfer to the registry.
2. On the transfers page, click on the arrow next to the edit button and select "Edit DNS"
3. Input your DNS settings to match what you have at your old drab registrar.
4. At this point you should be able to resolve DNS both at your old nameservers and at name.com's nameservers
5. But you are not done yet, you still need to browse to your old registrar and set the nameservers to the following: ns1.name.com,ns2.name.com, ns3.name.com, ns4.name.com
6. Now you can click on the link in the transfer approval email which will allow us to approve the transfer.
7. If your registrar allows you to acknowledge the transfer then you should wait 24 hours after you complete step 5 before you do so. Otherwise the old registrar could stop resolving your domains if anyone else has their nameservers cached.
8. If they don't allow you to acknowledge the transfer, we will have to wait the whole 5 day transfer period before the names are with name.com.
9 You're done! Yey!
Here, P-Mo ponders domain transfers. While some think he's simply doing some nervous chewing on his earbud, he's actually powering the Internet with his wind.
