Frequently Asked Questions About Operating System Software Updates

Review the following information before you upgrade the operating system.

Why can I not find the web executable that the Cisco Unified Communications application documentation specifies?

If you cannot locate a file on Cisco.com, Cisco removed the file from the web and replaced it with a newer version. Always install the version that is available on the web, unless the readme document states otherwise.

In what order should I apply the software updates?

Refer to Cisco IP Telephony Operating System, SQL Server, Security Updates for more information. See Table 2 to obtain the document.

How long does it take to upgrade the operating system?

The upgrade takes approximately 20-60 minutes, depending on the server type, the speed of the hardware, and the age of the components (BIOS, and so on).

Where do I find more information (release notes/readme) about the software update?

You can obtain the latest upgrade executable and version-specific readme document from the voice software cryptographic site on Cisco.com.

Be aware that the readme document may be a later version than the executable. Cisco recommends that you review the updated document for new information regarding the upgrade.

When should I install the software update?

Caution Cisco strongly recommends that you install the software update during off-peak hours or a maintenance window. Installing the software update may cause call-processing interruptions.
