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

# Getting started

Install Strapi alpha.20 globally on your computer. To do so run npm install strapi@3.0.0-alpha.20 -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.20 version) of your project.

Run npm install strapi@3.0.0-alpha.20 --save to update your strapi version.

# Update the Admin


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


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.

# Update services

For both bookshelf and mongoose, you will have to update all services of your generated API.

You will have to update one line of the fetchAll function.

Mongoose replace .populate(populate); by .populate(filters.populate || populate);. Bookshelf: replace withRelated: populate by withRelated: filters.populate || populate.

That's all, you have now upgraded to Strapi alpha.20.
