so I have one question: is there any fee to transfer domain? if yes , how much?
and do I need to register my domain again ?
@Feroz the cost is the same as a domain registration since a year of registration is added once the transfer is complete. You'll need to go into Namecheap and unlock the domain and get the authorization/EPP code from them. Then you can initiate the transfer here: https://www.godaddy.com/domains/domain-transfer
