Hi Chris,

thanks a lot for your reply and all the information!

It looks as though we should try to get the devkeys as soon as possible 
so we are prepared for whatever might happen in the future.

Other than that what I take away from this thread is that upgrading 
those XOs to the latest Sugar code will require quite a lot of 
preparation and work.
