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. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
