Cluster with multiple CCM version

Hello all.

I currently have a working enviromnet of Cisco Call manager Cluster with a CCM Publisher and a Subcrisber based on 7.1XXX version

we are currently planning to deploy a second suscriber addon to the existing enviroment to have One publisher and 2 suscribers in the Cluster.

my consern is that the new Subscriber is going to be implemented in version 8.X /

reason why I am posting this discussion is to make sure we can add a Subcriber 8.X to the cluster ?

                                                   PUB 7.1.xxxx

                         SUB 7.1.xxx                         SUB 8.1XXXX

please advise.

La vache.

Cluster with multiple CCM version

Hi there,

The new Subscriber would need to be the exact same 7.1 version

as the Publisher

Check out step # 6 below;

Add a New Node to an Existing Cluster

To add a new node to an existing cluster, follow the steps in Table 1.

Table 6     Adding a New Node to an Existing Cluster 

Task
For More Information

Step 1 

Before you make any changes to your existing cluster, be sure that you have a current backup file.

For more information, refer to the Disaster Recovery System Administration Guide.

Step 2 

Perform all pre-installation tasks that apply to your site.

For a list of pre-installation tasks, see Table 1.

Step 3 

Ensure that you have the appropriate number of licenses to support adding a new node.

For more information on specifying the required number of licenses, refer to the License Unit Calculator chapter in the Cisco Unified Communications Manager Administration Guide.

Step 4 

Before you install the new node, ensure that you have configured it on the first node.

From Cisco Unified Communications Manager Administration on the first node, choose System > Server and configure the IP address for the subsequent nodes. For more information, see the Cisco Unified Communications Manager Administration Guide.

Step 5 

Record the configuration settings for each server that you plan to install.

To record your configuration settings, see Table 9.

Step 6 

You must install the same software version on all nodes in the cluster. If you do not have the correct version on DVD, you need to either  download updated software from Cisco.com or follow the procedure for  applying a patch during the installation procedure.

For more information on the different installation options, see the "Installation Overview" section.

Step 7 

Follow the procedure to begin installing the software from the DVD to your server.

See "Starting the Installation" section.

Step 8 

If you need to upgrade the version of Cisco Unified Communications  Manager that you have on DVD, continue with the procedure for applying a  software patch.

See the "Applying a Patch" section.

Step 9 

Follow the procedure for performing the basic installation.

See "Performing the Basic Installation" section.

Step 10 

When the First Node Configuration displays, choose No to configure the new server as a subsequent node.

See Step 10 in the "Performing the Basic Installation" section.

Step 11 

Follow the procedure for configuring a subsequent node.

See the "Configuring a Subsequent Node" section.

Step 12 

Perform all post-installation tasks that apply to your site.

See Table 12.

Step 13 

If your cluster is running in mixed mode, ensure that you have your USB  key and the latest CTL Client installed on the PC that you use to  communicate with the first node. After you finish installing the new  node, you will need to update the CTL file on all nodes.

For more information, see "Applying Security to a New Node in a Secure Cluster" section.
