If you are upgrading from a version of WebNS software earlier than version 7.40,
be aware of the following Adaptive Session Redundancy (ASR) configuration
restrictions in WebNS software versions 7.40 and higher:
If your CSSs have mismatched chassis configurations (a different number of
•
Session Processors (SPs) in each CSS), ASR will not function after the
upgrade. Before you upgrade, ensure that both CSS chassis have the same
number of SPs.
If your CSSs meet the ASR requirement of having the same number of SPs in
•
each chassis, you must upgrade both CSSs to WebNS Version 7.40.
During the upgrade process, ASR does not function and you lose any sessions
•
that are in progress.
When upgrading the CSS software, you can use the upgrade script or manually
enter CLI commands. The upgrade script allows you to upgrade the CSS either
automatically or interactively by responding to script prompts. Either way, the
tasks that the script performs include:
•
Checking to see how many installed software versions are installed on the
CSS, and if the CSS contains the maximum number of installed software
versions, then deleting an older software version.
Archiving the running configuration to the startup configuration.
•
•
Copying the new ADI to the CSS boot-image directory.
Unpacking the new ADI.
•
Copying the scripts and user profiles from the older CSS software to the new
•
software. The copied scripts do not include Cisco-supplied scripts except
default-profile.
Setting the primary boot file to the new ADI.
•
Rebooting the CSS.
•
We recommend that you use the upgrade script because the upgrade script ensures
that the existing scripts and user profiles are copied to the new software.
When manually upgrading the CSS software, you must enter CLI commands to
perform the same tasks that the upgrade script would perform.
