Upgrading to Cisco Unified Contact Center Express, Release 8.5(1)
Important Considerations
• Make sure to complete the installation of Cisco Unified CCX 8.5(1) software
on the first node before installing the second node.
• Use the same security password on both the servers in the cluster if you plan
for an HA setup after the upgrade.
• Be aware that all user credentials that you enter while running the installation
wizard are case-sensitive.
• Carefully read the instructions that follow before you proceed with installing
Unified CCX 8.5(1).
• Procure all the necessary Unified CCX 8.5(1) licenses and keep them handy
after installing Unified CCX 8.5(1) server and before restoring the backed up
data on the Unified CCX 8.5(1) system. For more information on how to
procure the licenses, see the Installing Cisco Unified CCX and Cisco Unified
IP IVR, Release 8.5(1) available here:

• Before you install the second (subscriber) node, you must first add and
configure it on the first (publisher) node using the first node’s Web
Administration.
• Be aware that the demo license feature is not available when you upgrade
from a previous product version.
Note After you successfully restore the backed up data on the first node, you must
perform the JTAPI and Data Resync activity using the web interface of the Unified
CCX Administration. This activity should be performed before you proceed with
the Add to cluster operation.
• For a two-node setup, both the nodes in the cluster must be running the same
release / version of Unified CCX to perform the upgrade successfully.
• Installing the second node and then adding it to the cluster must be done
during off peak hours to avoid possible call drops during the formation of a
cluster.
• Perform the Add to Cluster operation only after you have completely restored
and upgraded the first node in a two-node setup.
