Migrating Accumulo to CDP
As Operational Database powered by Apache Accumulo (OpDB) is handled as a different service from Accumulo, in-place upgrade is not supported. However, an in-place data upgrade is supported from CDH 6 to CDP, or you can migrate your data and configuration to 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 the migration steps to migrate from Accumulo 1.x to OpDB, or if you are migrating from CDH 6 to CDP, you can follow the in-place data upgrade process.
