## Step A: Add worker nodes to the cluster
<a name="migrate-topic-add-w-cluster"></a>

1. On the web interface for the primary Conductor node, choose the **Cluster** page, then choose **Nodes**.

1. On the **Nodes** page, choose **Add Node**.

1. In the **Add Nodes to Cluster** dialog, do one of the following:
   + In **Node IP Address/s**, enter the IP address or range of IP addresses for multiple nodes and choose **Add**.
   + If your network has a DNS server, search for the node by its hostname:

     1. In **Lookup Node IP Address**, enter the hostname of the node that you're adding. You set the hostname during installation of the node.

     1. Choose the **search** icon.

     1. When Conductor Live displays the IP address that corresponds to the hostname, choose the plus sign beside the address to add it to the Node IP address list.

     1. Choose **Add**.

1. Still in the **Add Nodes to Cluster** dialog, add each node that will be a part of the cluster.

1. Verify that the nodes have been added to the list on the **Nodes** page and the correct information is shown:
   + The **Status** is **Online**.
   + The **Elemental Product** is the correct type of node, either Conductor Live or a worker.

1. If any worker nodes contain SDI cards, import the devices so that the Conductor node knows about them. Do the following:

   1. Still on the primary Conductor, go to **Nodes** page and find the first worker node that has an SDI card, Beside that node, choose the downward triangle and select **Import Devices**.

      Conductor Live detects the device and adds the device's configuration to the Conductor Live database.

   1. Repeat for every worker node that has an SDI card.

   If you don't import the devices, they won't appear in the Conductor Live web interface. You won't be able to specify these devices as video sources in a channel.

## Step B: Add worker nodes to redundancy groups

1. On the web interface for the primary Conductor node, choose the **Cluster** page, then choose **Redundancy**. In the navigation bar, choose the Elemental Live redundancy group.

1. On the **Active Nodes** tab, choose **Add to Active**. In the **Nodes** field, select the nodes to add to the group.

1. Choose **Add**.

1. On the **Backup Nodes** tab, choose **Add to Backup Nodes**. In the **Nodes** field, select the nodes to add to the group. Make sure that you add nodes in order, starting with the reserve node with the highest priority.

1. Choose **Add**.

1. If you have multiple Elemental Live redundancy groups, repeat this procedure on each group.

## Step C: Add node assignments
<a name="migrate-topic-add-w-channels"></a>

To assign channels back to a node, use the [list of channel assignments](migrate-std-prepare-node.md#migrate-std-capture-assignments) that you created for the node.

1. On the web interface for the primary Conductor node, display the **Channels** page, then choose **Tasks**, then choose **Change channel node assignments**. 

1. Select the channels that should all be assigned to one node, according to your list. Choose **Next**. 

1. On the **Select a new node** page, in **New Node**, choose the node for these channel.

1. Choose **Next**, then choose **Process Now**.
