Subject Re: Problem while migrating a single node cluster from 2.1 to 3.2
Date Sat, 30 Jan 2016 11:54:27 GMT
You need to upgrade first to C* 2.2 before migrating to C* 3.x

For each version, read the NEWS.txt file and follow the procedure:

>From 2.1.x to 2.2.x :
https://github.com/apache/cassandra/blob/cassandra-2.2/NEWS.txt

>From 2.2.x to 3.x:
https://github.com/apache/cassandra/blob/cassandra-3.0/NEWS.txt
