+When disabled, ``mongosync`` does not verify the migration. For
+alternative verification methods, see :ref:`c2c-verification`.
+
+This option provides a workaround for customers who 
+experience OOM kills when running ``mongosync`` with
+verification and cannot allocate more resources or tolerate
+restarting verification. It allows the migration to complete
+with verification disabled. Verification remains disabled
+for subsequent restarts and reversals.
+
+This option should not be used when ``mongosync`` is initially
+started. Instead, disable verification with the :ref:`/start
+<c2c-api-start>` request parameter ``verification.enabled:
+false`` since verification is enabled by default.
