DCT licensing
Data Control Tower has three tiers that determine available functionality and enabled use-cases via the DCT UI and API. They are Core, Self Service, and Enterprise, described in detail below.

DCT Enterprise
The full-featured, premium tier designed for large, complex Delphix deployments that require comprehensive data management capabilities. This tier includes the entire suite of DCT features, supporting unlimited engine connections and providing robust automation and control.
DCT for Self Service
Intended for Continuous Data-focused organizations that emphasize advanced developer workflows. This tier supports unlimited Continuous Data connections and delivers core DCT features alongside selected automation tools to enhance productivity.
DCT Core
Available to any customer with an active Continuous Data or Compliance engine license. This tier provides an entry-level experience aimed at smaller Delphix deployments or new users looking to explore DCT’s capabilities. This tier includes a limited feature set with a maximum of two Continuous Data (CD) connections and one Continuous Compliance (CC) connection, offering an accessible way to start managing data with DCT.
Engines dedicated to Hyperscale Compliance workflows will not be counted toward the engine quota under a license.
Navigate to the Admin tab, then select the License section on the left side. The UI will show restrictions for each license tier, the currently selected tier (DCT Enterprise, in this example), and the current engine counts.

Installing DCT 23.0.0 and beyond
DCT licenses will be defaulted to DCT Core at the time of installation. Once installed, administrators will be able to update their license by accessing the License section (under the Admin tab) and selecting DCT for Self Service or Enterprise.
Upgrading from DCT 22.0.0 and below
Users looking to upgrade to DCT 23.0.0 or later versions will now have to select their license post-upgrade. Once the upgrade is complete, DCT will default to DCT Enterprise to assure no functionality is lost. Users entitled to a lower tier of DCT must perform a license downgrade, which can be performed in the License section (under the Admin tab)
Downgrades will be blocked if prerequisites (e.g., DCT has more than the number of allowed engine connections for that license tier) are not met. This is to prevent loss of data as disconnecting an engine will remove the metadata associated with that engine.
Changing licenses
Upgrade the license tier via the UI (always possible).

Downgrading the license tier via the UI (only possible if the engine count restriction is satisfied for the target tier).
