Downgrading Your Software
• Merging configurations combines the current running configuration and the backed-up running
configuration.
• Replacing the running configuration uses the backed-up running configuration only.
• Skipping the step does not restore the backed-up running configuration.
Step 7 ASDM displays a status dialog box until the restore operation is finished.
Step 8 If you replaced or merged the running configuration, you will need to close ASDM and restart it. If you
did not restore the running configuration or the running configuration, you only need to refresh the
ASDM session for the changes to take effect.

Downgrading Your Software
When you upgrade to Version 8.3, your configuration is migrated. The old configuration is automatically
stored in flash memory. For example, when you upgrade from Version 8.2(1) to 8.3(1), the old 8.2(1)
configuration is stored in flash memory in a file called 8_2_1_0_startup_cfg.sav.
This section describes how to downgrade and includes the following topics:
• Information About Activation Key Compatibility, page 75-19
• Performing the Downgrade, page 75-20
Information About Activation Key Compatibility
Your activation key remains compatible if you upgrade to the latest version from any previous version.
However, you might have issues if you want to maintain downgrade capability:
• Downgrading to Version 8.1 or earlier versions—After you upgrade, if you activate additional
feature licenses that were introduced before 8.2, then the activation key continues to be compatible
with earlier versions if you downgrade. However if you activate feature licenses that were
introduced in Version 8.2 or later versions , then the activation key is not backwards compatible. If
you have an incompatible license key, then see the following guidelines:
–
If you previously entered an activation key in an earlier version, then the adaptive security
appliance uses that key (without any of the new licenses you activated in Version 8.2 or later
versions).
–
If you have a new system and do not have an earlier activation key, then you need to request a
new activation key compatible with the earlier version.
