💡 TIP

Feel free to join us on Slack (opens new window) and ask questions about the migration process.

# 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).

# 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.

# Update the Admin

💡 TIP

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.

# Update the Plugins

💡 TIP

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.

That's all, you have now upgraded to Strapi alpha.21.
