Migrate Citrix ADM single-server deployment to a high availability deployment

December 31, 2023

You can upgrade your Citrix ADM single server to a high availability deployment of two Citrix ADM servers. A high availability pair of Citrix ADM servers is in active-passive mode, and both the servers have the same configuration. In this type of active-passive deployment, one Citrix ADM server is configured as the primary node and the other as the secondary node. If for any reason, the primary node goes down, the secondary node takes over.

To migrate a Citrix ADM single server to a high availability pair, you need to provision a new Citrix ADM server node, configure it as the second Citrix ADM single server, and deploy both the Citrix ADM servers as a high availability pair.

Migrating a Citrix ADM single server to a high availability mode involves the following steps:

  1. Modifying the existing server node

  2. Provisioning the second server node

  3. Deploying the two nodes in HA mode

  4. Configuring the high availability pair

Modify the existing Citrix ADM server node

To migrate the Citrix ADM from single server to high availability mode, you have to change the initial deployment type of the server node to high availability mode.

  1. On a workstation or laptop, open the console of the existing Citrix ADM server node. For example, consider that you have deployed a Citrix ADM with IP address as 10.106.171.17 as a standalone server.

  2. Log on to Citrix ADM. The default credentials are nsroot and nsroot.

  3. In the shell prompt, type /mps/deployment_type.py, and press Enter.

  4. Select the deployment type as Citrix ADM server. If you do not select any option, by default, it is deployed as a server.

    Select the deployment type

  5. The deployment console prompts you to select the server deployment (as standalone). Type No to confirm the deployment as high availability pair.

  6. The console prompts you to select the (first server node). Enter Yes to confirm the node as the first server node.

  7. The console prompts you to restart the server.

  8. Type Yes to restart.

    Restart the ADM server

Provision the second server node

You have to provision the second server on your hypervisor. Use the same image file that you used to install the first server, or obtain an image file of the same version from the Citrix download site.

  1. Import the image file to your hypervisor, and then from the Console tab configure the initial network configuration options as explained on the following screen:

    Import the image file to your hypervisor

  2. After specifying the required IP addresses, in the shell prompt, type /mps/deployment_type.py, and press enter.

  3. Select the deployment type as Citrix ADM server.

  4. The deployment console prompts you to select the server deployment (as standalone). Type No to confirm the deployment as high availability pair.

    Select the server deployment

  5. The console then prompts you to select the (first server node). Type No to confirm the node as the second server node. Select the first server node

  6. Enter the first server’s IP address and password.

    Specify the server IP address

  7. Enter the floating IP address of the first node.

    Specify the floating IP address

  8. The console prompts you to restart the system. Enter Yes to restart.

Deploy the two servers in a high availability mode

To complete the installation process of the two server nodes as a high availability pair, you have to deploy these nodes from the GUI of the previously existing Citrix ADM server node. Internal communication between the two servers starts when you deploy the two server nodes.

Important

Before deploying high-availability nodes, ensure to change the default password.

  1. In a web browser, type the IP address of the previously existing Citrix ADM server node.

  2. In the User Name and Password fields, enter the administrator credentials.

  3. On the System tab, navigate to Deployment and click Deploy.

  4. A confirmation message appears. Click Yes.

    Note

    After you deploy Citrix ADM in high availability, you can either access the primary node or the floating IP address. You cannot access the secondary node from 12.1 release onwards.

  5. Though you have entered the floating IP while configuring the second server node, you have an option to update the FIP on the Systems page. Click HA Settings > Configure Floating IP Address for High Availability Mode. You can view the floating IP address you configured earlier. You can enter a new IP address and click OK.
