Chapter 1 Maintaining Your WAAS System
Upgrading the WAAS Software
WAAS Central Manager version 5.0.1 can manage WAE devices that are running version 4.2.1 and later
releases. Some WAAS Central Manager windows (with new features) are not applicable to WAAS
devices that are running a version lower than 5.0.1. If you modify the configuration in such windows,
the configuration is saved, but it has no effect on the device until the device is upgraded to version 5.0.1.
Note WAAS version 5.0 is not supported running in a mixed version WAAS network where any WAAS device
is running a software version lower than 4.2.1. If you have any WAAS devices running versions earlier
than 4.2.1, you must first upgrade them to version 4.2.1 (or a later version) before you install version 5.0
on the Central Manager. Do not upgrade any device to a version later than the existing Central Manager
version. After all devices and the Central Manager are running version 4.2.1 or later, then you can begin
the upgrade to version 5.0 on the WAAS Central Manager. Directly upgrading a device from version 4.0
or 4.1 to 5.0 is not supported.
Upgrading is supported only from certain older releases to a particular release. If you have a WAAS
device that is running a release from which upgrading to the desired release is not supported, first
upgrade the device to an intermediate supported release and then to the final desired release. For details
on what versions are supported for upgrades, see the Release Note for Cisco Wide Area Application
Services for the software version to which you want to upgrade.
Table 1-1 Checklist for Upgrading the WAAS Software
Task Additional Information and Instructions
1. Determine the current software version
running on your WAAS network.
Check the software version that you are currently using so when you go to
Cisco.com, you know if there is a newer version to download.
For more information, see the “Determining the Current Software Version”
section on page 1-3.
2. Obtain the new WAAS software version
from Cisco.com.
Visit Cisco.com to download a newer software version and place this file on
a local FTP or HTTP server.
For more information, see the “Obtaining the Latest Software Version from
Cisco.com” section on page 1-3.
3. Register the new software version with
the WAAS Central Manager.
Register the URL of the new software file so the WAAS Central Manager
knows where to go to access the file.
For more information, see the “Specifying the Location of the Software File
in the WAAS Central Manager GUI” section on page 1-3.
4. Upgrade your WAAS Central Manager. Upgrade the standby and primary WAAS Central Managers.
For more information, see the “Upgrading the WAAS Central Manager”
section on page 1-5.
5. Upgrade your WAAS devices using
Device Groups.
After upgrading the WAAS Central Manager, upgrade all your WAAS
devices that are members of a device group.
For more information, see the “Upgrading Multiple Devices Using Device
Groups” section on page 1-7.
6. Delete the software version file. After completely upgrading your WAAS network, you can remove the
software file if desired.
For more information, see the “Deleting a Software File” section on
page 1-8.
