I am looking for a chart that list how much free memory is needed to upgrade to a particular version. I know the PCS number is what avaya goes by, but I just inherited a system that I don't trust. I'm not sure that the motherboard is in the correct box and the PCS number is actually correct. I would like to find a way to actually confirm that the upgrade will work. I was hoping the I could run a monitor trace and check the free memory that was available. Thoughts from anyone?
