Chapter 1 Maintaining Your WAAS System
Upgrading the WAAS Software
If you need to downgrade or roll back the WAAS software to a lower version, first downgrade or roll
back the WAE devices, then the standby Central Manager (if applicable), and finally the primary Central
Manager. For more information about downgrading, see the Release Note for Cisco Wide Area
Application Services for your software version.
Determining the Current Software Version
To view the current software version running on any particular device, choose Devices > All Devices.
The All Devices window displays the software version for each device listed.
You can also click Devices > device-name or the Edit icon next to the name of a device in the Devices
window. The Device Dashboard window appears, listing the software version for that device.
Note The software version is not upgraded until a software upgrade has been successfully completed.
If a software upgrade is in progress, the version number displayed is the base version, not the
