I noticed that when upgrading from version 2.0 to 3.0, the script some how rebuilds the DB tables and wipe out existing data in the installation process. This can be damaging if users are not aware and their precious existing data can be wiped out by accident.

It would be helpful if the script allows user to pick an option whether to use existing data tables from an older version or create new table to avoid the potential issue above.

Generally this is a good app. Keep up the good work!
