There are ways to do the existing app forms and reports to VMP migration on a form by form basis. In the last application I converted we decided to leave all of the old reports alone. They wored in the VMP world just fine. So we just started with new reports being done in the VMP way.

The one of the apps has VMP based forms, converted forms and old forms that all coexist. It just takes a little forthoguth and planning.
