Thanks Steve. You've confirmed what I thought, partly. When I asked about the configuration, I was thinking about custom settings that might apply to our company's setup. My understanding is that when I upgrade, the old backed up data will no longer be readable/usable by the new system, and that the upgrade converts the data to the new format. I would think that part of the upgrade would be to convert custom settings (part of "the configuration") as needed. Is this correct? Thanks.
