I'm actually in the process of doing the same thing (only going from VFP6). I've done this several times in the past as well.

From what I've gathered there are several ways to go about it. In my case the application is only going to be around for another year or so and it's HUGE....so all I'm really doing is this:

SET ENGINEBEHAVIOR 70
SET TABLEVALIDATE TO 0
SET REPORTBEHAVIOR 80

...which for all practical purposes finishes the job (that and make sure anywhere you use the LOCAL statement you have comma's between the vars...

So if you have something like this:
LOCAL lcVar1 lcVar2 lcVar3

Change it too:
LOCAL lcVar1, lcVar2, lcVar3

If you do the above then in theory the app should compile and you'll be just fine. If you don't want to use the SET commands and make it more VFP9ish, then one of the things you have to keep in mind is how the GROUP BY clause has changed......
