Yes, all the switches should be the same, not only through the v.1 and v.2 versions, but also from the wet to surround, since the same template was used to create these ODFs. This could eventually allow importing settings from v.1 Wet into v.2 Surround! Unfortunately, I am not able to do this since I have only little knowlegde of Hauptwerk from the user side (since it isn't my product:))). I know how to make the sample sets and the ODFs, but I am not expert on the user settings of Hauptwerk. However, there are magicians among the users who might be able to do this.

The ODF IDs are the same from the v.1 However, the v.1 Wet ID is DIFFERENT from the v.1 (and hence also from v.2) Surround. So, the Wet. v.1 settings should not be touched by the Surround v.2. Hence the chance for the cross-import from the Wet v.1 into Surround v.2.
So, I would first back up everything, then I would
not uninstall v.1 to keep the settings untouched, then do the upgrade, then do the import from Wet v.1 into Surround v.2 (if it is possible) and see the result. Only then I would uninstall the Wet v.1 ODF.
