Upgrading from Other Versions of Cassandra or DataStax Community to DataStax Enterprise 2.2.x¶

The procedures listed in the previous section are based on upgrading from DataStax Community 1.0.x to DataStax Enterprise 2.2.x. Generally, these procedures work for upgrading from other releases to DataStax Enterprise 2.2.x. Exceptions are:

• Upgrading directly from versions 0.8.8 and 1.0.3-1.0.5 to 2.2.x does not work. These older versions generate cross-dc forwarding and are incompatible with Cassandra 1.1, a component of DataStax Enterprise 2.2.x. First upgrade to 0.8.11 or 1.0.11, then upgrade to 2.2.x.
• To upgrade from a Brisk release, contact Support.
• To upgrade from Cassandra 0.8 or earlier, refer to NEWS.txt.
