Thanks Dave !!! That makes sense.
I tried a few tables with "fake migration" (for grins and giggles) turned on and the code that generates the database/ stuff choked and puked all over the "foreign keys". I went back and left it as is, with everything expected as a "external" table, whcih is just as well, since I will have to dove tail this with a e-filing systems at some point.
