I found this to be the easiest way:
Install Pervasive Client on the SQL Server and create an ODBC connection to the Pervasive data.
Create a DTS package and select "Other data source" then select the Pervasive DSN and destination to a SQL database.
The data import is quite easy plus you can modify the package and schedule it. If you're looking to push the data from the Pervasive side, the method is limited. You can only export text files and there is no scheduling tool.
Good Luck.
