I know this is routine maintanace- I just started here. The old IT person has been gone for 5 months before they hired me. Your last point is exactly what I was thinking. Have a separate server to do the testing and move to that as production when ready. I think going back and forth between machines when upgrading ERPs is best. Thanks everyone.
it said the PERC H710 driver is out of date, with a Close button.
It also has a Load Driver link, not just a close button. It is trying to make sure it has the proper drivers for the OS to boot up after the upgrade. It doesn't think it has the proper driver for the PERC to function, so it is asking you to load one.
You should be able to follow the instructions on that page and click the Load Driver link and direct it to the .inf file I instructed you to extract out earlier. What happens when you do that?
