When upgrading from 7.05 to 7.12 it took about two hours for the upgrade to complete. We are upgrading the way we always have, clicking upgrade etc and letting it go through the process. Is there a faster way to do this with the SD cards now that we are missing? We have a handful of 24 hour operations that can't be down for that long while we fiddle with an upgrade. What are some of the tricks to the trade?
