Hi Sven,
Importing records from Article Manager to CMS Builder isn't straight forward, each installation of Article Manager requires a slightly different method to import the data. I'd recommend letting us carry out the import for you. If you send an e-mail to consulting@interactivetools.com, we can give you an estimate for importing the data.
Let me know if you have any questions!
Thanks!
Greg
