To avoid downtime, please follow these procedures:
1) Sign up an account using our online order form and it will be setup within the same business day. We will email you a "Welcome/Account Setup" letter which will include login details so you can upload your files to our server.
2) After you're done uploading your files, contact your domain name registrar and have your domain name pointed to our DNS numbers. You can find the DNS nameserver details in your Welcome letter.
3) Now, be patient. It will take about 12-72 hours for your registrar to update their DNS. Once it's updated, your domain name will point to your website that you have with us automatically.
4) After you confirm that your website is pointing to our nameservers, go ahead and cancel your account with your previous hosting company.
