I have a website created by A4Desk, can I transfer the content to A4Desk Pro? ( at top )

No, the project file of A4Desk Pro is different with A4Desk. Please copy your website content from your A4Desk to the A4Desk Pro template.

Any requirement on the webhosting server to host the website? ( at top )

Websites created by A4Desk Pro could run on all servers, as long as the viewer's browser have Adobe Flash Player installed.

If you don't have an existing webhosting server, you may consider our webhosting plan at: http://www.a4webhost.com
