If there isn't anything on NEWS.txt forbidding it, then it *should* be possible. That is the authoritative source for upgrade information. As noted by you, the only known restriction is that you upgrade from at least 2.1.9 as noted in the NEWS.txt entry.
But as always, and specially when doing an upgrade between major versions, make sure to test the upgrade in a staging environment first, as well as snapshot/backup your tables before the process. 2016-03-31 9:14 GMT-03:00 Steven Choo <ste...@iqnomy.com>: > Hi, > > Is it possible to update Cassandra from 2.1.9 to 3.x (e.g. 3.4) in one > step? > > The info about the tick-tock release schedule does not say anything > specific about it and the documentation on http://docs.datastax.com is > separated by 3.0 and 3.x. > Even though the info on > https://github.com/apache/cassandra/blob/trunk/NEWS.txt is clear about > updating from 2.1.9 to 3.0 and does not say anything specifically about the > tick-tock versions, I want to be sure its possible due to the earlier > upgrade requirements when upgrading between minor versions. > > PS.
