There are various ways to forward visitors from one domain/website to another. The so-called URL redirection is often recommended. In contrast to parking a domain name, a URL forwarding is feasible only if the domain name in question is hosted. What this means in simple terms is that you could still open any content in case you have a direct link to it and you can set up email addresses or subdomains and use them. This sort of function has many practical uses - if you choose to switch your domain, you can forward the site visitors, but the emails with the old one will still be active whenever you are getting in touch with clients or partners. When you have 2 identical sites and you need to rebuild one of them, you can forward the site visitors to the other website to prevent losing potential clients, while you will still be able to access the administration area for the first site and work on it.
