Trial V8 with V7 Pro installed

Have Version 7 pro can I trial version 8 to decide if I want to upgrade?

I could not - they complain that the license is not valid for version 8. Looks like i have to uninstall and do a new install with a trial version - without data from version 7

I got a new free license, deactivated the old v7 license, activated the new free 8 one - and could test the new version.
