Upgrading From 3.19 To 3.20

info

To follow the zero-downtime strategy when upgrading to 3.20, It is recommended to first migrate to latest 3.19.X and turn on the Celery worker to process all data migrations asynchronously. Otherwise, you will need to downtime your solution to ensure correct data migration.

Private media storage

Since Saleor 3.20 webhook event delivery payloads are stored as files using dedicated private storage. Make sure PRIVATE_FILE_STORAGE is configured properly in settings.py before upgrade.

Please refer to Amazon S3 or Google Cloud Storage (GCS) guidelines if you are using cloud storage.
