Hello folks,

I tried to upgrade ES v 1.7.5 to 5.0.0-alpha1 (single node) on VM centos7. First, I run API migration, I had only "blue" informations about the mappings. Second, I upgrade ES and tried to list indices. I found only .kibana indices 😕

Have you any idea why the upgrade failed?

Thanks !

You should upgrade to 2.x series first.

Thanks David for your answer. I thought it would be better to upgrade directly to v 5.0.0 if there is no difference between 2.x et 5.0.0 in terms of cluster mappings et query DSL.

It's a lucene compatilbility thing, you need to go to 2.X to upgrade to lucene 5, then to 5 for lucene 6.

Thank you Mark. To use Elasticseach Java Client v2.3.2, should I add Lucene (5.5.0) dependency in pom.xml or Maven pulls it by default?
