# Workflow Version History: View and Restore Past Versions

See every published version of a workflow, preview an older one, and restore it to your working copy before publishing again.

Every time you publish a workflow, Robylon saves a snapshot of it. Version history lets you see how the workflow looked at any point and roll back a change that did not work.

Open a workflow from **Settings → Workflows & AI Agents → Workflows**, then click the **History** icon (the clock) next to **Edit** at the top of the builder.

AI agents have their own, separate history. See [AI agent version history](https://www.robylon.ai/docs/ai-agents/version-history).

## How do drafts and published versions work?

A workflow has two current versions:

* **Working Copy:** the draft you edit in the builder. It shows **Not published yet** until you publish it. Your changes do not affect customers until then.
* **Live:** the version that runs on the workflow's triggers. It is read-only.

When you publish, the working copy becomes the live version and the old live version moves to **Previous Versions**, with the date, time and who published it. Publishing also replaces the workflow's triggers with the ones in the new version.

When you unpublish a workflow, its triggers stop, its status becomes **Paused**, and the latest version is marked as unpublished.

## How do I look at an older version?

Click the version in the **Version History** panel. The canvas shows that version's blocks and triggers so you can read them. Nothing changes until you restore it.

## How do I restore an older version?

<Steps>
  <Step title="Pick the version">
    In **Version History**, click the version you want or open its menu (**⋮**).
  </Step>
  <Step title="Restore it">
    Click **Restore this version**. The version replaces your working copy.
  </Step>
  <Step title="Check and publish">
    Review the workflow in the builder, then publish. Until you publish, the current live version keeps running.
  </Step>
</Steps>

<Danger>
Restoring overwrites your working copy, including any unpublished changes.

## Does restoring a workflow change its AI agents?

No. Restoring a workflow keeps the current version of any AI agent inside it. Agents are versioned separately: to roll back an agent, use [AI agent version history](https://www.robylon.ai/docs/ai-agents/version-history).

## Can I restore a simple automation?

No. Simple automations have no version history. Version restore is only available for workflows, not for [simple automations](https://www.robylon.ai/docs/simple-automations).
