We are currently using McAfee ePO 4.6.2 and planning to upgrade to 5.1.1 Can i get any document on how to upgrade from old version to new version? BTW ePO 4.6.2 is hosted on a windows 2003 SP2 32 bit server and we have around 5K users and different policies.
Unless you want to deploy the agent from the new ePO on-top of the old, and make sure you delete them out of the old, i don't think there is really any other way.. but maybe someone else can chime in regarding this.
You can also create a automatic response to transfer the systems from the old > new, but that is the same thing as doing it yourself.
You could go through this if you'd like, but seems like a pain:
