 <p>These steps refer to locally stored data such as POP accounts. For remote data (like IMAP) this is not 
necessary, since the data is still on the server and does not need to be manually transferred. You can set up 
the corresponding account in <app>Evolution</app> and the data will be downloaded.</p>
