To be honest, most corporations IT are very slow at upgrading, mainly due to the fact they are scared that system won't work after an upgrade, this really is legacy from Microsoft, Mac user should upgrade, just for the latest security measures if nothing else, but also a benefit to your company to be able to use latest software etcMark, you say that you have 2000 units running old operating system, not just out of date but years out of date, I think you should be looking for a new IT manager !! Seems he has not been doing his job !!
