Implementing a Cisco Unified Presence Multi-Node Deployment
Restrictions
Your hardware must comply with the multi-node hardware recommendations.
Procedure
- Upgrade the Cisco Unified Presence publisher node first.
- After you have upgraded the Cisco Unified Presence publisher node, upgrade each subsequent Cisco Unified Presence node in the cluster.
- Once all subscriber nodes have completed the upgrade, sequentially switch the software to the new software release one node at a time.
- Once the first subscriber has rebooted and has come back online with the new software release, switch the software release on the next subscriber node.
- Repeat Step 3 until the new software release is running on all subscriber nodes.

Adding a New Node
Follow this procedure if you need to add new nodes after a multi-node deployment is running.
Restrictions
Your hardware must comply with the multi-node hardware recommendations.
Procedure
- Create a new subcluster in the system topology interface (if required).
- Create a new node in the system topology interface.
- Install the new node.
- Assign the node to the subcluster (if required).
- The node will be pulled into the cluster but will not receive traffic until users are assigned to it.
- Assign users from other nodes to the new node as required.

Expanding the Cluster
Restrictions
- Your hardware must comply with the multi-node hardware recommendations.
- We strongly recommend that any node movements that involve unassigning or moving a large numbers of users is performed at off peak times. Such large operations can adversely impact performance.
Procedure
- Create the new subcluster(s) in the system topology interface (if required).
- Create the new nodes in the system topology interface.
- Install each new node.
- Assign the nodes to the (new) subclusters.
- Once all the nodes are online, assign users to the new nodes using the following user assignment options:
- Using the Find User Assignment feature, unassign selected users from each node, and use the User Assignment Mode parameter to reassign new users to new subcluster(s) and nodes.
- Using the Find User Assignment feature, manually move users to new nodes.
- Unassign all users, and then reassign the users to the cluster using the appropriate User Assignment Mode parameter setting for the whole cluster.
