# Upgrading the Matrix services This playbook not only installs the various Matrix services for you, but can also upgrade them as new versions are made available. To upgrade the services: - update your playbook directory (`git pull`), so you'd obtain everything new we've done - take a look at [the changelog](../CHANGELOG.md) to see if there have been any backward-incomptabile changes that you need to take care of - re-run the [playbook setup](installing.md): `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all` - restart the services: `ansible-playbook -i inventory/hosts setup.yml --tags=start` **Note**: major version upgrades are not done to the internal PostgreSQL database. To upgrade that one, refer to the [upgrading PostgreSQL document](maintenance-upgrading-postgres.md).
