Upgrading DLM
There are multiple components and clusters that are involved while upgrading DLM.
- Dataplane Service Platform and DLM App which are installed on the Dataplane host.
- HDP and DLM engine on the multiple HDP clusters.
These components and clusters may not be upgraded at once, but can be upgraded over a
period of time. DLM is designed to work across versions for these components. However,
the following upgrade order is recommended for performing the upgrade process.
- Upgrade Dataplane Platform and DLM App on the Dataplane host.
- Upgrade HDP and DLM engine on one cluster
- Upgrade HDP and DLM engine on another cluster
