I am preparing documentation for ISV certification. One of the requirements is providing an upgrade script. Does anybody know what an upgrade script is?
I am just about to do an upgrade for a customer that has an ISV's product.
Now if you are talking about NAV (Which I am not sure as you don't give a product and you posted in the Membership Questions) then I am assuming they are asking you to modify the standard upgrade process to include upgrading your product, and also an alteration to the Upgrade document that comes with the std upgrade toolkit to your product.
I could of course be wrong on all of this, so my answer really is, I suggest you contact MS :-)
