Installation Guide

Important Considerations

Upgrading to Cisco Unified Contact Center Express, Release 8.5(1)

• Make sure that Unified CCX and Unified CM data are in sync before

proceeding with the backup. If not please perform the data resync operation.

Note Configuration changes done through Cisco Unified CCX Administration after

Unified CM “Linux to Linux Upgrade” installation and before “Linux to Linux

Switch version” may not be migrated as part of the upgrade operation.

• You should always run PUT on the engine master node of the Unified CCX

server.

• Be aware that your call center remains down during the upgrade process.

• PUT backs up only 1.5 GB of latest recording data per node.

• PUT does not back up any user level files (prompts /grammar/documents) that

are stored outside of Unified CCX repository. You have to manually back up

these files and keep it in a safe network location.

• You must disable the Proxy setting on the server on which you intend to run

the backup activity. Otherwise, you might get the following error message:

Proxy settings are enabled on this server. Turn off all the proxy

settings prior to starting the backup operation.

• Perform the upgrade activity during off-peak hours or a maintenance window

to avoid impact from call-processing interruptions.

• You must have access to a secure FTP (SFTP) server to back up the data over

a network.

• Preferably use a SFTP server product that is certified with Cisco through the

Cisco Technology Developer Partner program (CTDP), such as GlobalScape.

However, Cisco allows you to use any SFTP server product.

• If you make any configuration changes during or after running PUT, the

system does not retain these changes when you upgrade.

• Be aware that when you install Unified CCX 8.5(1) on an existing server, the

hard drive gets formatted, and all existing data on the drive gets overwritten.

• Procure the necessary Unified CM license(s) and keep them handy.

• After running the PUT and before installing Unified CCX 8.5(1), you must

upgrade the system running Unified CM to the latest compatible version

using “Linux to Linux Upgrade” process and perform a switch version to

switch and activate the upgraded partition.
