Upgrading to Elasticsearch 5.0

Elasticsearch 5 version will be released soon. It's a good idea to start testing your cluster's compatibility with the new version. To help with the upgrade process, Elastic.co offers a tool called the Elasticsearch Migration Helper. Install this tool as an Elasticsearch 2.3 plugin:

sudo /usr/share/elasticsearch/bin/plugin install https://github.com/elastic/elasticsearch-migration/releases/download/v2.0-alpha2/elasticsearch-migration-2.0-alpha2.zip

Note

The Elasticsearch Migration Helper is only compatible with Elasticsearch 2.3.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
