# Decommissioning

Decommissiong is a mechanism in MinIO to drain older pools (usually with old hardware) and migrate the content from such pools to a newer pools (usually better hardware). Decommissioning spreads the data across all pools - for example, if you decommission `pool1`, all the data from `pool1` spreads across `pool2` and `pool3`.

## Features

     * <p>
     * The license type is one of the following values:
     * <ul>
     * <li>UNKNOWN if LICENSE file is not present for this dependency.</li>
     * <li>one SPDX identifier if the LICENSE content matches with an SPDX license.</li>
     * <li>Custom;URL if it's not an SPDX license,
     * URL is the Github URL to the LICENSE file in elasticsearch repository.</li>
     * </ul>
     *

 * programming language keywords.
 * <p>
 * The keywords are defined in a JSON file, although it's worth noting that what is and isn't a
 * keyword depends on the language and sometimes the context in which a keyword is used. For example,
 * `delete` is an operator in JavaScript, but it isn't in the keywords list for JavaScript or
 * TypeScript because it's OK to use `delete` as a method name.
