💡 TIP
Feel free to join us on Slack (opens new window) and ask questions about the migration process.
# Getting started
Install Strapi alpha.15 globally on your computer. To do so run npm install strapi@3.0.0-alpha.15 -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.15 version) of your project.
Run npm install strapi@3.0.0-alpha.15 --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.
# ⚠️ Bookshelf (Postgres and MySQL)
Go in diff files (opens new window) and search for following files:
Services: packages/strapi-generate-api/templates/bookshelf/service.template
Life cycle: packages/strapi-generate-model/templates/bookshelf/model.template
You will have to update all your service by applying the diff.
# ⚠️ Mongoose (Mongo)
Go in diff files (opens new window) and search for following files:
Service: packages/strapi-generate-api/templates/mongoose/service.template
You will have to update all your service by applying the diff.
# Providers
Like hook, middleware and plugin - we prefix plugin provider with provider Format: strapi-provider-[plugin_name]-[provider]
eg. strapi-email-sendmail become strapi-provider-email-sendmail
We still support the old format for next version to let time to providers maintainers to make migration.
That's all, you have now upgraded to Strapi alpha.15.
