new hosting provider you must make sure that both your old account and the new account that your created are active. Your website should be running. Check the connections that you have with your previous host. Once the hosting account content is totally copied on to your new provider (say, Go4hosting) servers, you should then change the name servers to the new providers. In case you require any assistance at any point of time regarding transfer
email hosting, you can always contact our support team, who are available 24/7 to assist you.
There are several possibilities that some of the requests may go to the previous hosting servers as your account with them is still active while some of the emails may come to the Go4hosting account. It generally takes anything between 24 to 72 hours for the DNS propagation to end and after that. all your emails will be directed to Go4hosting hosting account.
