You do not have to transfer domains to us in order to get them running from our network.
You can simply change the Nameserver records of any domains you wish to use on our systems or manage your own external DNS.
Our nameservers are given to you in your original welcome email that contains your account details and are available here:

If you do want Winserve to become your domains registrar then please follow the instructions here:
