+# Migration guide from alpha.20 to alpha.21
+
+**Here are the major changes:**
+
+- Fix timestamps issue about update data in MySQL
+- Fix production start
+
+**Useful links:**
+- Changelog: [https://github.com/strapi/strapi/releases/tag/v3.0.0-alpha.21](https://github.com/strapi/strapi/releases/tag/v3.0.0-alpha.21)
+- GitHub diff: [https://github.com/strapi/strapi/compare/v3.0.0-alpha.20...v3.0.0-alpha.21](https://github.com/strapi/strapi/compare/v3.0.0-alpha.20...v3.0.0-alpha.21)
+
+<br>
+
+::: note
+Feel free to [join us on Slack](http://slack.strapi.io) and ask questions about the migration process.
+:::
+
+<br>
+
+## Getting started
+
+Install Strapi `alpha.21` globally on your computer. To do so run `npm install strapi@3.0.0-alpha.21 -g`.
+
+When it's done, generate a new empty project `strapi new myNewProject` (don't pay attention to the database configuration).
+
+<br>
+
+## Update node modules
+
+Update the Strapi's dependencies version (move Strapi's dependencies to `3.0.0-alpha.21` version) of your project.
+
+Run `npm install strapi@3.0.0-alpha.21 --save` to update your strapi version.
+
+<br>
+
+## Update the Admin
+
+::: note
+If you performed updates in the Admin, you will have to manually migrate your changes.
+:::
+
+Delete your old admin folder and replace it with the new one.
+
+<br>
+
+## Update the Plugins
+
+::: note
+If you did a custom update on one of the plugins, you will have to manually migrate your update.
+:::
+
+Copy the fields and relations you had in your `/plugins/users-permissions/models/User.settings.json` and `/plugins/users-permissions/config/jwt.json` file in the new one.
+
+Then, delete your old `plugins` folder and replace it with the new one.
+
+<br>
+
+That's all, you have now upgraded to Strapi `alpha.21`.
