Hello all,

Just wanted to check if anyone has any experiences to share regarding

1.       the stability of vnodes in production

2.       upgrading to vnodes in production

We recently upgraded to 1.2.12 in production and were planning to turn on 
vnodes using the "adding a new datacenter" method vs using shuffle which seems 
to be not recommended. It helps that we were planning to add capacity to our 
Cassandra ring anyway. Our tests in QA so far have been good. If we do not 
upgrade now however, we will have to add the new hosts normally to the ring, 
and may not be able to add a new data center at a later point of time.

Thanks,
Arindam
