Hi:
There is no way to export settings from a 100 and then import them to a 200, nor would trying to hack this somehow be worth the time or effort, given the possibility of making a mess.
Just add the new 200 to your OBiTALK dashboard, and set it up from scratch. It actually takes less time than you may recall, especially now that you've had more experience with the products. You should be able to open another browser tab in the same browser (press Ctrl-T), and then log into the 100, and copy and paste the digit map or other custom setting values over to the 200. I'd suggest logging into the 100 via its local IP address to make the copy and paste steps a bit easier.
