We are currently running ACS 3.3 on a Windows 2003 member server of our domain. It has become necessary for the server administrators to upgrade our domain controllers from Windows 2003 to Windows 2008. Since we have no interest of running ACS on a Windows 2008 server, will we have to upgrade ACS as well to maintain our currently functionality (TACACS+ and RADIUS or wireless) or will things continue to work as is? I have been searching through documentation but I haven't been able to find an answer.
Any input would be greatly apprecaited.
