Upgrading Polr

---

To upgrade your Polr instance to the latest master or to a new release, you must back up your database and files before proceeding to avoid data loss.

Upgrading from 2.x:

• Back up your database and files
• Update your files by using git pull or downloading a release
• Run composer install --no-dev -o to ensure dependencies are up to date
• Migrate database with php artisan migrate to ensure database structure is up to date

Upgrading from 1.x:

There are breaking changes between 2.x and 1.x; it is not yet possible to automatically upgrade to 2.x.
