About upgrading

The DataStax Upgrade Guide provides detailed instructions on upgrading DataStax Enterprise, OpsCenter, DataStax Agents, and reverting to earlier versions.

DataStax driver changes

DataStax drivers come in two types:

  • DataStax drivers for DataStax Enterprise — for use by DSE 4.8 and later
  • DataStax drivers for Apache Cassandra™ — for use by Apache Cassandra™ and DSE 4.7 and earlier
Note: While the DataStax drivers for Apache Cassandra drivers can connect to DSE 5.0 and later clusters, DataStax strongly recommends upgrading to the DSE drivers. The DSE drivers provide functionality for all DataStax Enterprise features.

The DataStax Upgrade Guide provides detailed instructions on upgrading DataStax Enterprise, OpsCenter, DataStax Agents, DataStax drivers, and reverting to earlier versions.
