Is it possible to transfer my domain name registration from another registrar to Vikont and renew it through you instead?
Yes. You will however need to initiate a registrar transfer of your domain name in order to renew it through Vikont. By transferring your domain name to Vikont you are automatically renewing it for 1-year as well. i.e. If your domain name currently has 45 days to expiration, transferring it to Vikont will add 1 year to your current expiration date and leave you with 1 year and 45 days to expiration.
