ElasticSearch Java Version Compatibility

(raj shah) #1


I am planning to upgrade my Elastic Search cluster from v5.2.2 to v6.1.2 using rolling upgrade (5.2.2 to 5.6 to 6.1.2).

I currently have multiple Java applications pointed to my ES DB, that use Maven dependency of ES v5.2.2.

Since no downtime is required for rolling upgrades, will my Java applications (with Maven dependency ES v5.2.2) be compatible with the upgraded v6.1.2 ES DB?
If not, will it at least be compatible with v5.6 ES DB?

Kindly help.
Thanks in advance :slight_smile:

No. The Transport Client is not compatible across major versions.
