## Cluster Upgrade Best Practices To upgrade Docker Enterprise, you must individually upgrade each of the
following components:
1. Docker Engine - Enterprise.
2. [Universal Control Plane (UCP)](/ee/ucp/admin/install/upgrade/).
3. [Docker Trusted Registry (DTR)](/ee/dtr/admin/upgrade/).
Because some components become temporarily unavailable during an upgrade, schedule upgrades to occur outside of
peak business hours to minimize impact to your business.
