+    You may have redundant grant scopes if you applied a grant to a scope and the scope also inherited the grant from the <code>this</code>, <code>children</code>, or <code>descendants</code> options. Redundant grant scopes could cause performance issues. As of Boundary version 0.19.3, redundant grant scopes are no longer permitted.

+    When you run the <code>boundary database migrate</code> command to upgrade a cluster to Boundary version 0.19.3, the migration will fail with a message if the database contains any redundant grant scopes. The migration tool provides the following command to automatically repair the grant scopes:
+    <br /><br />
+    <code>boundary database migrate -repair=oss:97001</code>
+    <br /><br />
+    Run the command to remove any redundant grant scopes from roles. Any individually granted scopes that are already covered by <code>descendants</code> or <code>children</code> grants are considered invalid and removed. When the migration is complete, the migration tool produces a message that details any changes.
