ACS 5.1 Upgrade

[normanzhang]

Is upgrade for CSACSE-1113-K9 appliance running 4.2.0.124 to 5.1 supported?

This is not supported...ACS 4.2 can be installed on 1120 with a downgrade...

Note: ACS 5.0 is not supported on 1113 HW.

Are there plans from Cisco to provide upgrade path from 4.2 to 5.x for 1113 HW?

I don't believe that will happen, unless a new Hardware Upgrade Kit is created, look at this for the System memory comparison:

ACS 4.2:

ACS 5.1

Also a new DVD would need to be developed since ACS Appliance Versions are hardware specific...I suppose is not impossible to use the same HW, but I haven't heard of any near plans to occur.

Now keep in mind that the upgrade from ACS 4.X to 5.X is consider a full Migration...lots of differences in the way you manage your Clients, Users, Policies...
