# Migration guide from alpha.11 to alpha.12

This migration guide is a mix of migrations from 3.0.0-alpha.11.1 to 3.0.0-alpha.11.2, 3.0.0-alpha.11.2 to 3.0.0-alpha.11.3 and from 3.0.0-alpha.11.3 to 3.0.0-alpha.12.1.3.

💡 TIP

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

# Getting started

Install Strapi alpha.12.1.3 globally on your computer. To do so run npm install strapi@3.0.0-alpha.12.1.3 -g.

When it's done, generate a new empty project strapi new myNewProject (don't pay attention to the database configuration).

# Configurations

You will have to update just 1 file: package.json

Edit the Strapi's dependencies version: (move Strapi's dependencies to 3.0.0-alpha.12.1.3 version) in package.json file

{
  "dependencies": {
    "lodash": "4.x.x",
    "strapi": "3.0.0-alpha.12.1.3",
    "strapi-mongoose": "3.0.0-alpha.12"
  }
}

# Update the Admin

Delete your old admin folder and replace it by the new one.

# Update the Plugins

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 by the new one.

# Update roles

💡 TIP

This update is if you come from version before alpha-11.2

Update type of Guest role to public in your database. You can also update name and description:

{
  "name": "Public",
  "description": "Default role given to unauthenticated user.",
  "type": "public"
}

Create Authenticated role:

{
  "name": "Authenticated",
  "description": "Default role given to authenticated user.",
  "type": "authenticated"
}

In Users & Permissions > Advanced in admin panel update default role to Authenticated

You also will have to reset your roles permissions.

# Update bookshelf filters

💡 TIP

This update is if you come from version before alpha-11.3

You will have to replace your fetchAll services queries of your generated API:

_.forEach(convertedParams.where, (where, key) => {
  if (_.isArray(where.value)) {
    for (const value in where.value) {
      qb[value ? 'where' : 'orWhere'](key, where.symbol, where.value[value]);
    }
  } else {
    qb.where(key, where.symbol, where.value);
  }
});

if (convertedParams.sort) {
  qb.orderBy(convertedParams.sort.key, convertedParams.sort.order);
}

qb.offset(convertedParams.start);

qb.limit(convertedParams.limit);

That's all, you have now upgraded to Strapi alpha.12.1.3.
