Elasticsearch Migration Checker v1.18

This plugin will run a series of checks against your Elasticsearch cluster to determine whether you can upgrade directly to Elasticsearch version 2.x, or whether you will need to make changes to your data before doing so.

It will run on Elasticsearch versions 0.90.x to 1.x only.

Read more about important changes in the Breaking Changes documentation online.

Each check is given a color:

• Everything is OK.
• An advisory note that something has changed. No action needed.
• You can upgrade directly, but you are using deprecated functionality which will not be available in version 2.x.
• You cannot upgrade without fixing this problem.

IMPORTANT Checks are limited only to data that is stored in the cluster, such as cluster and index settings, mappings, and segments. It does not take settings files or your use of the API into account. You should still test your application thoroughly and backup your data before upgrading.
