upgrade cassandra from 2.0.6 to 2.1.2

[wyang <wy...@v5.cn>]

I looked some upgrade documentations and am a little puzzled.


According tohttps://github.com/apache/cassandra/blob/cassandra-2.1/NEWS.txt, “Rolling upgrades from anything pre-2.0.7 is not supported”. It means we should upgrade to 2.0.7 or later first? Can we rolling upgrade to 2.0.7? Do we need upgradestables after that? It seems nothing specific to note upgrading between 2.0.6 and 2.0.7 in NEWS.txt


Any advice will be kindly appreciated

AFAIK, no one is formally testing upgrades from the middle of a series,
so...

+1, users should consider any other upgrade path likely to be effectively
untested and therefore not explicitly supported.

Yes.  It is, in general, a best practice to upgrade to the latest bug fix
release before doing an upgrade to the next point release.
