Command History, Preferences, and Favorites
If you uninstall Release 12.0, you will lose the Command History, preferences,

these files when uninstalling Release 12.0, see “Maintaining Preference Files
After Uninstalling” in Chapter 1 of the Release Notes.

browser, those favorites may point to an incorrect or invalid location in Release
12.1. You will need to delete any invalid favorites and add those favorites
again.
