Thanks James -- I am fairy confident that the upgrade would be easy and go smoothly in our little network, and I know that you and Sandeep could help if it didn't.
My situation is a little different -- I have 5 more months committed to keeping the practice open, then I'm done..
I am choosing between two small probablity states -- on the one hand the chance of failure of the upgrade is small, and on the other, the chance of the current setup failing before Dec 31 is small.
