Journey to CDP Data Center
Migrate to CDP Data Center
-
There are multiple scenarios where migration is the best or most feasible approach. For example, you:
- Have capacity on a new cluster.
- Are doing a hardware refresh such as for greater capacity or performance.
- Do not want to disturb existing workloads.
- Can move workloads one at a time.
- Do not want any downtime.
- Have an existing instance of CDH and HDP that does not have a direct upgrade supported.
There are several tools available, including:
Workload XM
Enables you to migrate or shift workloads after analyzing them, and helps you move workloads one by one.
Replication Manager
Helps you replicate and copy the data and metadata.
The migration process is to:
- Set up the new cluster.
- Identify the candidate workloads.
- Copy the data and metadata.
- Migrate and test the workloads.
- Promote the new cluster and workloads into production.
- Decommission the legacy cluster.
- Depending on hardware compatibility, add the nodes to the new CDP Data Center cluster for additional capacity.
This process enables you to perform a rolling migration of the cluster, by both:
- Deploying new hardware.
- Repurposing existing hardware by gradually migrating data and workloads to the new cluster.
An overview of the migration process is shown in Figure 6.
