leupold, thanks for the feedback. Here are a few details.
We have been working with this non profit for many years and built their initial site on DNN 2.1.2. They have over 3,000 members.
We built this current website (http://www.blueribbonschools.com/ ) in 2005 using DNN 3 and because of some political issues in our client's organization it got shelved until just recently. There are some pretty complex custom modules that allow for the submission and processing of educational best practices. Then there are basic and advanced search tools for educational best practices.
The submission of a best practice is tied to a DNN user and we had created a view that pulled in data from the three aspnet_ tables that I mentioned above.
We got the go ahead to upgrade it to DNN 4 and launch it. We checked out pretty much everything after the upgrade, but there is one part that is not working because apparently when new users are created there is no data being written to the aspnet_Profile table. I noticed that the aspnet_Profile table is there even in new 4.5.3 installs, but apparently nothing is being written to that table anymore. Am I right about that?
Now all profile data is being written to the UserProfile table it appears. So I need to look and see if all the existing members' profile data is there and if so, I can start to get the required info from there instead of the view we created.
Let me know if any of my assumptions or understanding appear to be incorrect.
Thanks.
