noted Tyler...and many thanks.. well, I read cassandra jira issues and just followed one of the comment 

https://issues.apache.org/jira/browse/CASSANDRA-5740
In general, I thought we always advised to upgrade through the 'major' revs, 1.0 -> 1.1 -> 1.2. Or, at least, I think that's the advice now

but I will read carefully for the diff between 1.0.12 to latest of 1.1.x... i think there should be many changes.

I'm not aware of any good reason to put 1.1.0 in the middle there.  I would go straight from 1.0.12 to the latest 1.1.x.
