I have a large app that I am thinking of migrating to Creator 5.  However, given past experiences with Zoho upgrades and the rather nebulous Zoho list of "degraded functionality" in Creator 5, I am nervous about changing anything.  I would appreciate hearing other users' experiences in migrating to Creator 5. 

I am particularly interested in the following functionality that is used heavily in my app:

1.  We have over 1,000 active Portal users, with a steady stream of new adds (about 200 a year)
2. We take Paypal payments for various activities conducted through the portal (typically 1-5 a day)

3. We have some publicly published forms that take Paypal payments.  The forms are accessible by anyone on the internet via links on our public website.  During peak season we may be doing as many as 100 of these transactions a day.

4. We make extensive use of "Restrict Visibility" on Reports to limit what reports Portal users can see and what they can do with the reports that they do see.  I saw one Zoho writeup that said that "Restrict Visibility has been eliminated.

Thank you in advance for your replies.
