+
+::: 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.19` globally on your computer. To do so run `npm install strapi@3.0.0-alpha.19 -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.19` version) of your project.
+
+Run `npm install strapi@3.0.0-alpha.19 --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.
+
+## Production environment
+
+If you deploy your application on a server that you don't have write file access you will have to update your procution config file.
+In `config/environments/production/server.json` file you have to add `production` key with `true` as value.
+
+```
+{
+  ...
+  "port": "${process.env.PORT || 1337}",
+  "production": true,
+  "proxy": {
+    "enabled": false
+  },
+  ...
+}
+```
+
+<br>
+
+That's all, you have now upgraded to Strapi `alpha.19`.
