Converting as fast as possible but not in production....... but it is getting pretty close.
Obviously most of the work in conversion is in the UI.
Depending on the complexity of your app..... conversion for many things is a snap.... other things (especially if you have something a bit funky in V6) are
a bit more of a challenge.
Additionally.... you will probably (and in many cases should) change your app to take advantage of some of the new features... ie. Nested Queries, Modeless WIndows etc.
All in all am pretty pleased. Haven't done any Mobile / Tablet yet but Ben reports it is a quantum leap better.
I have written a new app over the last week which is not huge but has some complexities in it and am now doing final tweaking and testing..... I will wait until final released
but would be pretty confident with it in production so far.
Codrin's Ranfab app has been converted and looks very sweet.
The Zero to Hero Beginners Workshop for the conference will be all in V7.
