Sharepoint 2010 and WSS 3.0

<p>Hi,</p><p>we currently use Sharepoint 2010 for a number of different depts and&nbsp;Project Server 2010 but we have inherited a WSS 3.0 installation from a company&nbsp;acquisuired. This WSS is on another AD domain but we would like to somehow import it into our Sharepoint 2010. The WSS has it's own content Database but what would be the best approach to deal with the import?</p><p>Thanks.</p><p></p>
