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.
