I would recommend doing clean installation, with importing templates and database (backup -> restore).
Alternatively, you could do this:
1. Copy all the folders from Business package except files, backup, cache, templates and themes and conf.php file in root.
2. Make sure to change license key in conf.php located in the root folder of your Vivvo installation
3. Refresh your license by entering this address in your web browser: http://www.example.com/admin/index.php?force_reset=1
Of course, it is strongly recommended not to perform this on live, production website.
