Hi guys.
I need to upgrade my existing and working 0.9 elasticsearch installation to
v1.0. Now, I've been searching for a tutorial or guide, but just found some
tips and items to take note of. Backup all the existing data and downtime.

..
.
So, is there a guide to follow? is it enough to backup /data dir and
upgrade /bin and /lib dirs?
Hope someone has upgraded and can help me out here.
Thanks!!

It'll depend a lot on the version you are running in 0.90.N. due to
underlying lucene changes
We rebuilt our cluster and reindexed, as we took the chance to make a few
changes to data and cluster structures and we had the capacity.

You'll need to do a full cluster restart from .90.x to 1.x (i.e. need to
bring down all nodes). There is some information here to help reduce
recovery/startup churn:
[http://www.elasticsearch.org/webinars/elasticsearch-pre-flight-checklist/](http://www.elasticsearch.org/webinars/elasticsearch-pre-flight-checklist/)
But in general:
1. Stop all queries/indexing jobs
2. Flush your indexes: curl -XPOST "localhost:9200/\_flush"
3. Shutdown your cluster: curl -XPOST "localhost:9200/\_shutdown"
4. Backup all your data/ and config/ folders (from all nodes if you have
multiple data folders/nodes) - This is important in case the upgrade fails!
5. Per node, uninstall your current ES. Be careful not to delete the data
folders and your config/ files
6. Per node, install new ES and pull in your config/\* files from previous
install
7. Verify all config files in all nodes and all data folders
8. Start all nodes one by one
