6 days for an upgrade is bull I work as a Systems Administrator for a large company and my clients would laugh my out of their plants if I told them an upgrade would take 6 days.:banghead: There is nothing that I can think that they could be doing that would take a 6 day shut down of that system. A total replacement of the system shouldn't take more than 12 hours cut over time. If a complete rebuild / replacement is being done then that should happen on the side and moved into place once the new system is completed and tested. I have to wonder if PA is trying to test the limits of what they can get away with.
