I'm taking over a project of deploying Office 2010 to about 1600 machines. The previous person who was in charge of this had only deployed to about 185 machines. The person stated that only 25 machines could be updated at a time. Also, he stated that if a user is using any office products, the upgrade will fail. Is this true? Also, how many machines can i deploy at a time. I was thinking maybe using GPO to push office 2010. Any help would be greatly appreciated.
