Hi there

Thanks for all!

Greetings

How did you initially install ES?

Downloading the .zip and configuring elasticsearch.yml

Read the release notes for all versions between the versions in question, unpack the new zip file, migrate the configuration file, move the data directory into place (unless the data directory is elsewhere). If you're upgrading from 1.x to 2.x you should use the migration plugin prior to the upgrade.

Thanks for all

I am using ES 2.0.0 but I need upgrade it to latest version that is 2.3.5 to install Shield. Is the plugin only for the versions 1.x to 2.x?.
