For what it is worth, I performed the upgrade this morning. In the end I waited until the 1.0 release.
I basically upgraded as follows: 1) shutdown logstash agents reading from redis so write traffic to es cluster stopped 2) shutdown the es cluster entirely 3) one by one, upgrade the machines with es 1.0.0 and start the nodes It took quite some time for the cluster to go green again. Probably index conversion. Otherwise, everything still seems to work. For incremental updates in the future, I'd be curious to know what other people's experience is with performing rolling upgrades instead. I decided not to risk it here but we will have a live system soon depending on es and a full cluster shutdown would be highly inconvenient then.
