# Irreversibility of Unity Catalog Enablement

**Irreversibility of Unity Catalog Enablement** refers to the permanent nature of assigning a Unity Catalog [[metastore|Metastore]] to a Databricks workspace. Once a workspace is enabled for Unity Catalog, the action cannot be undone, and the workspace transitions to account‑level identity management. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

## Overview

Enabling a workspace for Unity Catalog means the workspace is attached to a [[Unity Catalog metastore]], the top‑level container for data organization. This allows users in the workspace to potentially access data shared across multiple workspaces in the account, enables automatic data access auditing, and activates identity federation so that administrators manage users, groups, and service principals centrally through the account console and other account‑level interfaces. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

## Irreversibility Statement

The Databricks documentation explicitly states:

> **Be aware that enabling a workspace for Unity Catalog cannot be reversed. Once you enable the workspace, you will manage users, groups, and service principals for this workspace using account-level interfaces.** ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

This means that after the [[metastore|Metastore]] assignment is complete, there is no supported operation to detach the workspace from Unity Catalog or revert to a non‑Unity Catalog state.

## Implications

### Identity Management Shift

After enablement, user, group, and service principal administration must be performed through account‑level endpoints rather than workspace‑level endpoints. Any existing automation that uses workspace‑level SCIM provisioning or Terraform must be updated to refer to account endpoints. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

### Workspace Admin Privileges

Workspace admins retain their ability to manage workspace‑level tasks (adding users, creating clusters, etc.), but their default access to Unity Catalog objects may differ depending on whether the workspace was enabled automatically or manually. Account admins can restrict workspace admin privileges using the `RestrictWorkspaceAdmins` setting. When planning an enablement, administrators should review existing workspace admin assignments and the impact on data access control. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

### Data Access Boundaries

To isolate data access by workspace after enablement, administrators can use [[Workspace-Catalog Binding|Workspace‑catalog binding]] to limit which catalogs are visible from a particular workspace, and external location workspace binding to restrict storage access. These configurations are optional but recommended for environments that require strict separation (e.g., production vs. development). ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]

## Considerations Before Enabling

- **Review privilege distributions:** Understand that workspace admins gain (or retain) certain privileges over Unity Catalog objects. Carefully evaluate who holds the workspace admin role before enablement. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]
- **Update automation:** Convert any workspace‑level SCIM provisioning scripts or Terraform configurations to use account‑level endpoints. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]
- **Plan for irreversibility:** Because the enablement is permanent, all downstream processes (identity management, data access policies, audit logging) must be designed with Unity Catalog in mind from the start. ^[enable-a-workspace-for-unity-catalog-databricks-on-aws.md]
