Important Considerations

Before you start upgrading your Unified CCX system, make sure you have met

the following requirements:

• Ensure that you connect each Unified CCX node to an uninterruptible power

supply (UPS) to provide backup power and protect your system.

Caution Failure to connect the Unified CCX nodes to a UPS may result in damage to

physical media and require a new installation of Unified CCX.

• Use Backup and Restore system to take the regular backup of the Unified

CCX 7.0(1) SR5 server before you start the backup process using the Cisco

Unified CCX Pre-Upgrade Tool (PUT).

• Make sure that all the nodes in the Unified CCX 7.0(1) SR5 cluster are up and

running before you start the backup process using the PUT.

• Stop and disable Cisco Security Agent (CSA) and other antivirus software

applications, if any, running on the Unified CCX 7.0(1) SR5 nodes in the

cluster before starting the Windows to Linux Upgrade.

• You can continue to have your Call center operational while PUT is being

installed. However, if the call center is operational during the backup

operation, you might lose newly-generated call record data.
