What name servers are you using?
If you are using the name servers of your hosting company or you host your own custom name servers, then you are all set.
You can simply place
a domain transfer order and follow the instructions to transfer your domain name.
When domain names are transferred between registrars the name servers for the domain name will remain the same
so you have nothing to worry about.
If you are using name servers of your current domain registrar, then you need to take some additional steps
after you place
a transfer order.
As we mentioned earlier, your name servers will remain the same when your domain name is transferred away from your current domain registrar.
The problem exists because your current domain registrar's name servers will stop responding to the DNS queries for your domain name as soon as your domain name is transferred out.
What comes after is the website and email downtime.
