When updating Distributed DDNS components, you must upgrade each component in the system. BlueCat recommends updating the components in the following order:
- Distributed DDNS Application Node
- Distributed DDNS Data Node
- Distributed DDNS Service Node
Before updating any components, first remove the Data Node and Service Node from the Application Node. You can do so from the Application Node UI. Removing a node only removes its data from the database and does not impact operation of the node.
