In-place upgrade with new nodes for Cloudera Data Warehouse 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 Data Service, which reduces the time required and lowers risk.
In-place upgrade and migration is a two-step process. To get to Cloudera Data Warehouse
on premises, you must:
- Upgrade an existing CDH cluster to Cloudera Base on premises
- Install Cloudera Data Warehouse Data Service on the new hardware alongside the base cluster and then move your compute workloads from Cloudera Base on premises to Cloudera Data Warehouse Data Service
The following diagram shows running the Cloudera Data Warehouse Data Service on premises 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:
