1. Cisco ACS /Solution Engine I think, the dedicated appliance, unknown version)
2. Cisco Security Manager 3.1
Are upgrades possible, or purchase of lastest version of the product is the only way out?
What do we need for upgrading?
Are there specific codes or new need to buy new products?
In case of buying new products, which are the configurations?
Your response will be appreciated.
The ACS appliance has been released with at least three different major releases - 3.x, 4.x, and 5.x. If you have ACS 4.2 on an 1120 appliance, you can upgrade to the latest (5.3) on the same hardware. Anything else will require a new appliance (or use a VM solution).
For CSM, to upgrade you would need to go to 3.3. first and then to the current (4.2) CSM release. The necessary licenses are described in this product bulletin.
It would probably be easier and cleaner to just build a new installation in both cases. Both products' architecture and db schema have changed significantly. The upgrade SKUs will probably save you some in licensing costs although both products have undergone changes in how they are licensed.
Note that CSM will be coming out with a new version 4.3 later this spring.
