i have a website was hosted on a server but now i have change its name server and host name as well, i uploaded this website to new server completely but i have not suspended its account in previous whm means its also there all mails and every thing, now i am confused that is this website fetching code or mail from other server because mails are running with previous server ip, how's it possible, am i need to delete the account in last whm or suspend it. I am too confused? what are the necessary things to do when changing server.
