In-place upgrade with new nodes for CDW Data Service
The age and hardware refresh cycle of legacy clusters is an important consideration when deciding on the in-place upgrade strategy. To add new hardware to the base cluster this mechanism is the best choice. Adding new hardware to the base cluster makes it simpler to set up the Cloudera Data Warehouse (CDW) Data Service, which reduces the time required and lowers risk.
- Upgrade an existing CDH cluster to CDP Private Cloud base
- Install CDW Data Service on the new hardware alongside the base cluster and then move your compute workloads from CDP Private Cloud base to CDW Data Service
The following diagram shows running the CDW Data Service on Private Cloud on the new hardware alongside the base cluster after an in-place upgrade from CDH. HW stands for hardware and NW stands for new workloads:
