There are some rumors online that it would be difficult, or even impossible, to change hosting. The question is, should you trust the rumors and not to change hosting companies? You do not want there to be any problems with your site.
You certainly do not need to worry about changing hosting providers. Are you unhappy with your current web host, or have found an offer that is too good to be missed, if so then you should definitely change. However you do need to think about a few things before you initiate the move to change the hosting to be as smooth as possible.
Firstly, you should make a full backup of all the files you have stored on the web site. Log in to the web site and go into the browser and download the files, either manually or via FTP. Also makes a backup on any email you need to keep.
Secondly, you should consider whether the hosting provider you want to which to offers all the services and features you need. It can be about databases, versions of the scripting language and support for certain software.
A third thing you must not forget is to make sure you have your login details to the operator (registrar) with which you registered your domain name. When you change hosting providers, you must redirect your domains to the new web servers or so-called DNS servers. If your registrar is the same as your current web host, you need not worry about this.
