# Deactivating servers linked to Teradata
<a name="USER_SQLServerTeradata.Deactivate"></a>

To deactivate linked servers to Teradata, remove the `ODBC_TERADATA` option from its option group.

**Important**  
Deleting the option doesn't delete the linked server configurations on the DB instance. You must manually drop them to remove them from the DB instance.  
You can reactivate the `ODBC_TERADATA` after removal to reuse the linked server configurations that were previously configured on the DB instance.
