We are currently running Cisco ACS solution engine 188.8.131.52 and using a Windows Domain Controller as a remote agent.
We now need to upgrade the ACS to 4.1
1. Do I need to upgrade the remote agent on the Domain Controller as well?
2. Can any PC/laptop on the network be used as a Distribution server?
3. After an initial backup and then upgrading to 184.108.40.206 do I need to do another backup before upgrading to 4.1?
