I am at one of the customer location who has recently purchased ACS (1120 hardware platform) with image 5.0. I downgraded it to 22.214.171.124 with downgrade CD that came along with the box. The reason for downgrade was I needed to replicate this acs with one of my older 4.1 box of 1113 platform.Now I want the both ACS to integrate with AD for VPN user authentication . My AD architecture is Windows 2k8 server with 64 bit.
Now Please help me to best judge the ACS version to upgrade 126.96.36.199 to 188.8.131.52.x for this requirement.
I tried ACS 184.108.40.206 upgrading to ACS 220.127.116.11.17 but I got the error as "the image is not supported for platform 1120". Also let me know is not possible to upgrade ACS 1120 platform to ACS 18.104.22.168.x .
Waiting fo valuable help.
