I did it myself and didn't have any problems. The only time Kodak has to do the update is if the OS has to be upgraded at the same time. For example, our Prinergy 5 ran on Windows 2003 Server while Prinergy 6 has to have Windows 2008 Server. Kodak has to do the OS update if it needs to be done at that time. We had Kodak do the OS update and a few months later I did the upgrade from Prinergy 5 to Prinergy 6.
