Is there a direct tech support email? There only seems to be a form for Upgrade Appts through the portal.
Also, instead of upgrading, I'm planning on testing out the version 8 on a different server altogether. Is it possible to install V8 clean, then import the 7.1.3 data?
Yes, you can do a clean install, then restore and tune the database.
If that server has terminal services, you will wnat to test that capability after install, you may find some issues.
