Migration choices to migrate workloads to CDP Private Cloud Base
To migrate Impala workloads from CDH to CDP Private Cloud Base, you can perform a side-car migration. If your goal is to migrate the workloads to Cloudera Data Warehouse (CDW) Private Cloud, then perform an in-place upgrade of CDH nodes to CDP Private Cloud Base and then migrate the Impala workloads to CDW Private Cloud on new nodes.
Each mechanism has common aspects of work, risk mitigation, and successful outcomes expected across all paths from legacy distributions into CDP. 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 CDW on Private Cloud.
