Migration choices to migrate workloads to Cloudera Base on premises

To migrate Impala workloads from CDH to Cloudera Base on premises, you can perform a side-car migration. If your goal is to migrate the workloads to Cloudera Data Warehouse on premises, then perform an in-place upgrade of CDH nodes to Cloudera Base on premises and then migrate the Impala workloads to Cloudera Data Warehouse on premises on new nodes.

Each mechanism has common aspects of work, risk mitigation, and successful outcomes expected across all paths from legacy distributions into Cloudera. Both paths include assessing the workloads, testing, validating, and minimizing workload unavailability during the move. Cloudera recommends the in-place upgrade and migration method to migrate Impala workloads from CDH to Cloudera Data Warehouse on premises.
