I'm interested in doing the same.
For right now the only method might be to do the following:
1. Create a copy of all the tables used within an MS-Access database utilizing the SOTA MAS 90 ODBC driver.
2. Write queries to update these tables from links.
3. Save these MS-Access tables and then upload them to MS-SQL.
I'll look at various MAS forums as well to see if there are any alternatives.
