Is it possible to migrate ACS 4.2 from appliance to microsoft server 2003?
has any one tried it before???
There is no problem to migrate from ACS appliance to ACS for windows.
If you would like to do this, it is better that your ACS for window runs the same version of code as ACS appliance.
You can do a backup on ACS appliance and then restore it on ACS for windows.
