Upgrading

Graphite 0.9.14 now requires a Django version of at least 1.4. Ensure this dependency is satisfied before updating graphite-web.

As always, comparing the example config files with existing ones is recommended to ensure awareness of any new features.

Graphite-web’s application database will need to be upgraded for a new Django fixture. It’s a good idea to backup the database before proceeding with the migration. The following will upgrade a SQLite database:

sudo cp /opt/graphite/storage/graphite.db \
      /opt/graphite/storage/graphite.db.backup-`date +%Y%m%d_%H%M%S`
sudo PYTHONPATH=/opt/graphite/webapp django-admin.py syncdb \
      --noinput --no-initial-data --settings=graphite.settings
