Effects of Upgrading or Downgrading to or from Software
Release A4(2.0) or Later
This section describes the licensing feature interactions when you upgrade to software version A4(2.0)
and later, and then downgrade to software version A4(1.1), A3(2.7), or earlier.
Caution If you migrate from software version A4(1.1) to A4(2.0), keep in mind that the new software features in
A4(1.1) are not supported in A4(2.0) and you will lose those A4(1.1) features. However, you will gain
the dynamic workload scaling (DWS) feature that is supported in A4(2.0). Conversely, if you migrate
from software version A4(2.0) to software version A4(1.1), you will lose the DWS feature, but you will
gain the 20 plus features that are new in software version A4(1.1). For details about the A4(1.1) features,
see the Release Note, Cisco 4700 Series ACE Application Control Engine Appliance for software version
A4(1.1). For details about the DWS feature, see the Server Load-Balancing Guide, Cisco ACE
Application Control Engine for software version A4(2.0).
ACE Appliance with Software Release A4(1.1), A3(2.7), and Earlier Licenses
When you upgrade to software version A4(2.0) or later from an earlier version, you may obtain new
feature capabilities (maximum limits for compression, SSL TPS, and the number of virtual contexts),
depending on your current license levels, without having to buy new software licenses. After you have
upgraded to software version A4(2.0), if you need to downgrade to an earlier software version, the earlier
software version reverts to the earlier feature limits that you had prior to the upgrade. For example, if
you acquired additional virtual contexts (a maximum of 20) when you upgraded to software version
A4(2.0) or later, when you downgrade to software version A3(2.7), A4(1.1), or earlier, you lose those
additional contexts and their configurations, and your contexts are limited again to a maximum of 5.
