If you’re planning to move from one host to another, you need a really easy way to grab all of your account data. cPanel makes this very simple. Your host can seamlessly transfer all of your site content, databases, mailboxes, and preferences at once.
With other control panels, this isn’t quite so simple. Some don’t have any export options, and the ones that do will produce an export file incompatible with cPanel.
Since cPanel is the most common control panel on shared hosting accounts, this can present a problem for hosting providers because they have to move everything manually. cPanel to cPanel transfer is very efficient and has a very low risk of data loss. It’s quick and easy for hosts to transfer cPanel customers, which is why they often provide free migration.
