Our company is a pharmaceutical production plant.
We are planning to upgrade the operating systems on most P.C.s from Windows XP to Windows 7.
The systems were qualified by a validation process based on the OS being Win XP.
What actions should be taken in order to keep the systems qualified after upgrading to Win7 OS?
For OTS systems- Is a supplier declaration that the system is compatible to Windows 7 enough to keep the system in a validated state?
