+### Leftover resources
+
+As of MTC 1.5.0, Rollback intentionally leaves some resources created by Direct Volume Migration behind on the source and the target clusters. The leftover resources assist debugging a failed migration. All of these resources are automatically deleted when performing a subsequent migration and do not require manual cleanup.
+
+On the source side, _ConfigMap_, _Secret_ and Rsync _Pods_ are left behind in each of the namespaces present in the _MigPlan_. 
+
+On the destination side, _ConfigMap_, _Secret_, _Service_ and _Route_ resources are left behind in each of the namespaces present in the _MigPlan_.
+
+Please note that these resources are only left behind when a migration fails for debugging purposes. A subsequent successful migration will automatically clean them up before reaching completion.
