I've asked a Comcast employee to help you. You should expect a reply in this thread.
Hello Sujanawale2, first you would need to make sure your new home is serviceable. Please click on this link and scroll down to the middle of the page then input your address, if the location is serviceable you can click "transfer services" under the "Shop/Upgrade" tab on the site. Please let me know if you have any other questions or concerns.
