Ray, here's the deal:  

• You can export your existing farm/field structure to the GS2. 
• Use the GS2 in the field to drive new boundaries.
• Use the Import/Export -> Business Hierarchies to read the setup data back from the GS2.   This will update the boundaries in EASi Suite with those that you drove and logged onto the GS2.

Now, we've used this with people running the Itec Pro version of the GS2.   I would like to see a card image from a conventional GS2 with driven boundaries, just to make sure that they are logged in the same way.

As always... make a backup of your database before doing anything this significant.
