Why does Toad 2.1 install into its own directory when upgrading from a Toad 2.0? (4296559)

I want to upgrade from Toad 2.0 to 2.1 but Toad 2.1 does not install on top of the 2.0 directory.   Should I select the 2.0 directory to install 2.1 into?

Installing into a new folder was due to a name change from Toad for Data Analysis to Toad for Data Analysts.

While the name change may seem trivial, migrating all the previous settings, file paths, etc. was not.   It is  recommended  that you keep the 2.1 directory and migrate the settings from 2.0 when prompted during the 2.1 installation.   2.0 can be uninstalled once you are satisfied  that  2.1 has all the necessary setting migrated over.
