1)The newer version ACS is ACS 5.1 and runs on a  Cisco ACS 1121 hardware.

More from the release notes here :


Otherwise you can also build a VMWare machine to install it on :


2 and 4)

The migration documentation is from version 4.x to 5.1 and is available here :


There will be a lot of manual intervention and analysis involved in the migration.

Take note the following :

The most efficient way to make optimal use of the  new policy model is to rebuild policies by using the new policy model.  This method entails creating appropriate Identity Groups, Network Device  Groups (NDGs), conditions, authorization profiles, and rules.

3) It is a linux based appliance.

Hi Tan,

Sev3 SR 614126335 : ACS 4.2 upgrade

Following is our upgrade path,

1) 3.3.3-->4.1
2) 4.1 -->4.2

Before you start upgrade  process make sure to take a backup of your ACS configuration.

Here are the steps to upgrade ACS  windows, On server take a backup for 3.3  and keep it handy.

1) Run the setup of 4.1  During this process, it will  prompt you to upgrade existing configuration. Make sure you check that option  else we will loose the database. Now you need to hit next.next to finish the 4.1  upgrade.

2) Now on 4.1 take a backup and keep  it handy. Run the setup of 4.2  During this process, it will prompt you to  upgrade existing configuration. Make sure you check that option else we will  loose the database. Now you need to hit next.next to finish the 4.2 upgrade.

You can use Win2003 (Migration machine) for above.
