Migrate Operational Database powered by Apache Accumulo
Follow these steps to migrate service configuration and data to Operational Database powered by Apache Accumulo (OpDB).
Cloudera does not support in-place upgrade because OpDB is handled as a different service from Accumulo, so the configuration changes would be lost on upgrade. You can use these migration steps to migrate from Apache Accumulo 1.x to OpDB.
