# utf8mb4 database upgrader for WP-CLI
|
|
|
|
Force upgrade your WordPress database to utf8mb4 via WP-CLI.
|
|
|
|
## Description
|
|
|
|
This WordPress plugin is designed to upgrade your WordPress database to utf8mb4 via WP-CLI. The plugin will go through each table in your database and upgrade its collation to `utf8mb4_unicode_ci`.
|
|
|
|
Why would you do this? Maybe your database missed this conversion when WordPress 4.2 first shipped. If it did, you may be [affecting your site's performance](https://www.percona.com/blog/charset-and-collation-settings-impact-on-mysql-performance/).
|
|
|
|
## Installation
|
|
|
|
1. Upload the plugin files to the `/wp-content/plugins/utf8mb4-database-upgrader-cli` directory, or install the plugin through the WordPress plugins screen directly.
|
|
2. The plugin can be run via WP-CLI with the following command: `wp upgrade_utf8mb4`.
|
|
|
|
## Requirements
|
|
|
|
- WordPress 4.2 or higher
|
|
- PHP 7.0 or higher
|
|
|
|
## Usage

|

```

wp upgrade_utf8mb4

The output will look like this:
