Software Release Information
Note
When you upgrade the controller to an intermediate software release, wait until all of the access
points joined to the controller are upgraded to the intermediate release before you install the
5.2.193.0 software. In large networks, it can take some time to download the software on each
access point.

Cisco recommends that you install the Cisco Unified Wireless Network Controller Boot Software
5.2.157.0 ER.aes file on all controller platforms. This file resolves CSCsm03461 and is necessary
in order for you to view the version information for ER.aes files in the output of the show sysinfo
CLI command. If you do not install this ER.aes file, your controller does not obtain the fix for this
defect, and “N/A” appears in the Emergency Image Version field in the output of this command.

Note
The ER .aes files are independent from the controller software files. You can run any
controller software file with any ER.aes file. However, installing the latest boot software file
(5.2.157.0 ER.aes) ensures that the boot software modifications in all of the previous and
current boot software ER.aes files are installed.

Caution
If you require a downgrade from one release to another, you may lose the configuration from your
current release. The workaround is to reload the previous controller configuration files saved on the
backup server or to reconfigure the controller.
