You should be able to import the 3.1 CVP Studio app into CVP 4.0 and not have problems. The issues I've heard of are:
1.The subdialog start and return elements are no longer voice elements, so they no longer have a General, Audio, or Data tab. So anything you might've had in those tabs of the element's config will be gone.
2.You may have to delete the .settings file before importing into Studio. Since the .settings file is pretty different now, there may be issues here. I've not experienced issues, but have heard that others have.
3. The Subdialog Return element can't be used as an "Error" element anymore, so if you had that in your 3.1 app, you'll have to use an Audio element as your Error element now.
4.In the latest version of CVP 4.0 if you have any custom elements that create session data that isn't an integer or a string, then you break the ability to log detail information to the "CVP Reporting Database".
5. If using Tomcat, the port number has changed from 8080 to 7000 and it starts up by default at boot time as the 'Cisco VXML Server Service' (or something like that)
