BMS Continuum Software Upgrade

I am new to computer validation and am looking for any advice on what may need to be verified. I am working with a previously validated system that is receiving 1. new PCs 2. new server 3. software upgrade 4. integrating two buildings onto the company network with all new IP addresses (the points at one building are not qualified and will be in a seperate effort). At this time i have not been given any documentation illustrating what changes with the software upgrade. Again if anyone can provide information it would be greatly appreciated!

If the system was validated then that will be your start. Any changes to the parts that is critical under the old validation must be revalidated.

Hi
I am starting a similar project to the above - just wondering how it worked out for you?
