# Customize the legacy workflow

> How to customize legacy workflow behavior in Atoti Limits for limits and incidents, including custom workflow tasks and settings - note these workflows are deprecated and will be removed in a future release

<Warning>
  These legacy workflows still exist for backward compatibility and to simplify migration efforts but
  will be removed in a future release. Please use the newer workflows in your product. This page
  exists
  only for helping users migrate and will be removed in a future release.
</Warning>

This section outlines how to customize the default Business Process Management (BPMN) workflows in Atoti Limits.

BPMN workflows are visual diagrams that use a standardized notation to model and understand business
processes, enabling automation and streamlining of workflows. The workflows themselves may be simple
or highly complex, depending on the business requirements.

Atoti Limits comes with a set of out-of-the-box workflows that are used to manage the lifecycle
of limits and incidents. These workflows are designed in such a way that they are generic enough to
cover a broad range of use cases but not specific enough that they can only be used for one purpose.
We expect users to implement their own workflows to suit their business needs, using ours as samples.

We use [Activiti](https://www.activiti.org/) as the BPMN engine and [BPMN.io](https://www.bpmn.io/)
to help visualize the workflows. For more information on including a custom workflow
in your application project, please see the following sections.
