+## Update Root Domain Unit Owner
+
+The root domain unit owner for your Amazon SageMaker domain can be changed using AWS CLI or API. This procedure is helpful when the original IAM role/user no longer exists and ownership needs to be replaced.
+
+To use the AWS CLI to update the root domain unit owner, use the update-root-domain-unit-owner command. The IAM user or role initiating the call needs to have the datazone:UpdateRootDomainUnitOwner permission.
+
+Considerations:
+
+  1. Domain ID, Current Owner, and New Owner are required.
+
+  2. The new owner needs to exist as a user in the domain.
+
+  3. SSO users/groups are referenced using their display name. IAM users/groups are referenced using their ARN.
+
+
+
+
+Example command:
+    
+    
+      aws datazone update-root-domain-unit-owner \
+      --domain-identifier DOMAIN_ID \
+      --current-owner CURRENT_OWNER \
+      --new-owner NEW_OWNER
+
