I'm running a two-node cluster with Elasticsearch 0.90.11. I want to
upgrade to the newest version (1.1.1), but I'm not entirely sure on how to
do it. 0.90.11 is based on Lucene 4.6.1 and 1.1.1 on Lucene 4.7.2. Can I do
the following:
1. stop node 1.
2. install 1.1.1 on node 1.
3. copy data folder to 1.1.1.
4. start node 1 and wait for it to synchronize.
5. stop node 2.
6. install 1.1.1 on node 2.
7. copy data folder to 1.1.1.
8. start node 2 and wait for it to synchronize.
I can live with downtime if not possible otherwise.

I guess the upgrade will upgrade to latest lucene automatically.
1. stop node 1.
2. install 1.1.1 on node 1.
\*[NOT REQUIRED] \*_3. copy data folder to 1.1.1._
3. start node 1 and wait for it to synchronize.
Let me know how it goes.

Important part is:
0.90.x
1.x
Restart Upgrade
So you need to stop the whole cluster and restart.

Following the upgrade guide worked perfectly. Thank you very much for your
help.

Hi Thomas,
I am following the same steps as you listed.
I had one query I would be thankful if you can help me out.
After copying the data and config folder to the latest elasticsearch
version when I restart the elasticsearch 1.1.1 server,
I see two nodes in the same cluster(instead of one).
Can you tell me how this second node is created?
Thanks,
Ayush
