User Migration Between IM and Presence Service Clusters
This section describes how to migrate users between IM and Presence Service clusters. You must complete the following procedures in the order in which they are presented:
-
Export the contact lists of the migrating users from their current home cluster.
-
Disable the migrating users for IM and Presence Service and Cisco Jabber on their current home cluster from Cisco Unified Communications Manager.
-
If LDAP Sync is enabled on Cisco Unified Communications Manager:
-
move the users to the new Organization Unit, from which their new cluster synchronizes its information
-
synchronize the users to the new home Cisco Unified Communications Manager.
-
-
If LDAP Sync is not enabled on Cisco Unified Communications Manager, manually provision the migrating users on Cisco Unified Communications Manager.
-
Enable users for IM and Presence Service and Cisco Jabber.
-
Import contact lists to the new home cluster to restore contact list data for migrated users.
Before You Begin
Complete the following tasks:
-
Perform a full DRS of the current cluster and the new home cluster. See the Disaster Recovery System Administration Guide for more information.
-
Ensure that the following services are running:
-
Cisco Intercluster Sync Agent
-
Cisco AXL Web Service
-
Cisco Sync Agent
-
-
Run the Troubleshooter and ensure that there are no Intercluster Sync Agent issues reported. All Intercluster Sync Agent issues reported on the Troubleshooter must be resolved before proceeding with this procedure.
-
Cisco recommends that the Allow users to view the availability of other users without being prompted for approval setting is enabled. To enable this setting, choose . Any change to this setting requires a restart of the Cisco XCP Router.
-
Cisco recommends that the following settings are set to No Limit:
-
Maximum Contact List Size (per user)
-
Maximum Watchers (per user)
To configure these settings, choose
.
-
-
Ensure that the users to be migrated are licensed for Cisco Unified Presence or Cisco Jabber on their current (pre-migration) home cluster only. If these users are licensed on any other cluster, they need to be fully unlicensed before proceeding with the following procedures.
Export User Contact Lists
Complete this procedure to export the contact lists of the migrating from their current cluster.
Procedure
Step 1 |
Export the contact lists of the migrating users from the current home cluster.
|
Step 2 |
Monitor the status of the contact list export job.
|
Step 3 |
Download the contact list export file and store it for use later when the user migration is complete.
|
What to do next
Proceed to unlicense the users.
Disable Users for IM and Presence Service
The following procedure describes how to disable a migrating user for IM and Presence Service and Cisco Jabber on their current home cluster.
For information about how to update users in bulk, see the Cisco Unified Communications Manager Bulk Administration Guide.
Procedure
Step 1 |
Choose . |
Step 2 |
Use the filters to find the user that you want to disable for IM and Presence Service. |
Step 3 |
In the End User Configuration screen, uncheck Enable User for Unified CM IM and Presence. |
Step 4 |
Click Save. |
Move Users to New Cluster
The procedure to move the users to the new cluster differs depending on whether LDAP Sync is enabled on Cisco Unified Communications Manager.
LDAP Sync Enabled on Cisco Unified Communications Manager
If LDAP Sync is enabled on Cisco Unified Communications Manager, you must move users to the new Organizational Unit and synchronize the users to the new home cluster.
Move Users To New Organizational Unit
If LDAP Sync is enabled on Cisco Unified Communications Manager, you must move the users to the new Organizational Unit (OU) from which their new cluster synchronizes if the deployment uses a separate LDAP structure (OU divided) for each cluster, where users are only synchronized from LDAP to their home cluster.
![]() Note |
You do not need to move the users if the deployment uses a flat LDAP structure, that is, all users are synchronized to all Cisco Unified Communications Manager and IM and Presence Service clusters where users are licensed to only one cluster. |
For more information about how to move the migrating users to the relevant OU of the new home cluster, see the LDAP Administration documentation.
After you move the users, you must delete the LDAP entries from the old LDAP cluster.
What to do next
Proceed to synchronize the users to the new home cluster.
Synchronize Users To New Home Cluster
If LDAP is enabled on Cisco Unified Communications Manager, you must synchronize the users to the new home Cisco Unified Communications Manager cluster. You can do this manually on Cisco Unified Communications Manager or you can wait for a scheduled synchronization on Cisco Unified Communications Manager.
To manually force the synchronization on Cisco Unified Communications Manager, complete the following procedure.
Procedure
Step 1 |
From Cisco Unified CM Administration, choose . |
Step 2 |
Click Perform Full Sync Now. |
What to do next
Proceed to enable users for IM and Presence Service and license users on the new cluster.
LDAP Sync Not Enabled On Cisco Unified Communications Manager
If LDAP Sync is not enabled on Cisco Unified Communications Manager, you must manually provision the users on the new Cisco Unified Communications Manager cluster. See the Cisco Unified Communications Manager Administration Guide for more information.
Enable Users For IM and Presence Service On New Cluster
When the users have been synchronized, or manually provisioned, on the new home cluster, you must enable the users for IM and Presence Service and Cisco Jabber.
Procedure
Step 1 |
From Cisco Unified CM Administration, choose . |
Step 2 |
Use the filters to find the user that you want to enable for IM and Presence Service. |
Step 3 |
In the End User Configuration screen, check Enable User for Unified CM IM and Presence. |
Step 4 |
Click Save. |
Step 5 |
Provision the users on Cisco Unified Communications Manager for Phone and CSF. See the Cisco Unified Communications Manager Administration Guide for more information. |
For information about how to update users in bulk, see the Cisco Unified Communications Manager Bulk Administration Guide.
What to do next
Proceed to import contact lists on the new home cluster.
Import Contact Lists On Home Cluster
You must import the contact lists to restore contact data for the migrated users.
Procedure
Step 1 |
Upload the previously exported contact list CSV file.
|
Step 2 |
Run the import contact list job.
|
Step 3 |
Monitor the contact list import status. |
