Best thing to do is write to your current
Domain provider and say that you no longer
wish to have them as your provider and that
you intend on transferring your domain name
to another provider. Contact your new
provider and tell them that you wish to
transfer your current domain name from your
old provider to this new company.. they
should take you step by step ono how to do
it.... or if they're good enough they'll do
all the hard work for you.
