Topic: Transfer of forum data frpm PunBB to DotNetNuke

We have been useing PunBB forum for some years.  However, all our Webpages and webshop will soon be integrated in DotNetNuke.  Is there any way to transfer the data? Are our designated technician given Ftp access or database access - or is anyone with you able to export the raw data?
Best regards
