Hey everybody,
I have a question regarding the migration of the indices to a new cluster
seamlessly. Let me first describe the situation:
I have a project which uses Elasticsearch since a few weeks ago. This is our
first Elasticsearch project, and as we are satisfied with it, we decided to
dedicate a cluster of 3 nodes to run Elasticsearch (lets call it
"newcluster"). It is up and running separately from our old 1-node
Elasticsearch installation ("oldcluster"). We want to migrate everything to
newcluster, and turn oldcluster off. All 4 servers are running Ubuntu Server,
Elasticsearch is installed from the official deb package, oldcluster is
0.90.10 and newcluster 1.0.0.
I came up with the following solution, but I'm not sure it will work:
- Upgrade oldcluster to 1.0.0 (tested it in dev, should work)
- Backup the index (we have only one index right now) in case something goes
wrong.
- Change oldcluster's name to newcluster.
- Wait until the nodes synchronize themselves (how can I check if they're in
sync?)
- Shut down oldcluster.
Thank you very much,
Attila
