The application runs on a SP 2003 Server.<br />Now we plan to migrate the application to IP &amp; SP 2010. <br /><br />My Problem is - what is the best way to upgrade the form so that the code works after the upgrade and that it is also possible to open the old xml instances.<br />Is there a best practise way or are there some donts which I have to consider.</p> <p>Thanks in advance</p> <p>grims</p>
