Migration Process


Hi all,

I'd like to know if there's a process when we want to upgrade elasticsearch's version, and that if possible without knowing the version, just generally.

Is it better to create a new cluster and give to data.path the value of the old data and then use the migrate API ?
Or maybe create a new cluster and make a snapshot of the old data and a restore in the new cluster ?
Or maybe something else ????

Thanks a lot.

P.S : If there's really a need, my old cluster use Elastic 2.1.1 and my new 2.3.3. I know v5 is here...

There's snapshot and restore, or if you have 5.0 you can do remote-reindex.
Otherwise take a look at https://www.elastic.co/guide/en/elasticsearch/reference/5.0/setup-upgrade.html


Thanks a lot.

I'm gone take a look.
