Is there a way to migrade elasticsearch 5.0.0-alpha5 index to 5.1.1?

(Lin Zhao) #1

The alpha5 release note implies alpha5 indices are not compatible with GA:

IMPORTANT: This is an alpha release and is intended for testing purposes only. Indices created in this version will not be compatible with Elasticsearch 5.0.0 GA.

I tried upgrading form alpha5 to 5.1.1 and the old indices are gone. Is there officially a way to migrade alpha5 data to 5.1.1? Snapshot and restore seems promising but I'd like to ask for a quick answer before testing it out.

Alphas and betas aren't likely to upgrade cleanly. Even if they looked like they'd work something weird is likely to happen down the line. I'd try reindex-from-remote even though it is slow because it is more sure to work.
