Upgrading to Unified CCX 8.5(1)
8
Upgrading to Cisco Unified Contact Center Express, Release 8.5(1)
• Delete the migrated Cisco Tool for Auto-Registered Phone Support (TAPS)
component from the recently upgraded Unified CCX 8.5(1) server to avoid
data conflicts. After a successful upgrade, you must download the TAPS from
the upgraded Unified CM server again and re-upload this component to the
Unified CCX 8.5(1) server.
• For Unified CCX 8.5(x), prompt file names are case-senstive. Ensure that the
prompt file names in the system exactly match the prompt file names used in
scripts. You can complete this task before or after the upgrade. You can
update the names in the scripts or in the system.
Upgrading to Unified CCX 8.5(1)
This section describes how to prepare for upgrade and perform the entire upgrade
process on Unified CCX 7.0(1) SR5 servers in order to move to Unified CCX,
Release 8.5(1). As stated earlier, the entire upgrade process is carried out in
following four phases:
• Backup Phase, page 8
• Installation Phase, page 20
• Restore Phase, page 21
Backup Phase
In the backup phase, you back up your Unified CCX cluster with a tool offered by
Cisco, called the Pre-Upgrade Tool (PUT). This tool facilitates the process of
backing up data from your Unified CCX cluster.
Since Unified CCX 7.0(1) SR5 still supports two-node clusters with high
availability (HA), you should run PUT on the engine master node. However,
before you run PUT to complete the backup operation in an HA setup, make sure
that both the nodes in the cluster are up and accessible. PUT retrieves the backed
up data from the standby servers programmatically and move the complete backup
TAR file to the SFTP location provided by you.
