# Comparing process flow versions

## Introduction

There may be times when it's useful to compare two versions of a process flow - for example, you might wish to compare the current `draft` version with the current `deployed` version, before deploying changes that you've completed in the `draft`.

The `compare versions` feature allows you to select any two versions of a given process flow for comparison.

## The steps

{% stepper %}
{% step %}
**Access version details for the required process flow**

Open [settings](/product-documentation/process-flows/building-process-flows/process-flow-settings.md) for the required process flow and scroll down to the `versions` panel.

{% hint style="info" %}
For detailed instructions, please refer to [Accessing process flow versions](/product-documentation/process-flows/building-process-flows/process-flow-versioning/accessing-process-flow-versions.md).
{% endhint %}
{% endstep %}

{% step %}
**Select the compare option**

Click the `compare versions` button (at the top of the `versions` panel), for example:

{% endstep %}

{% step %}
**Choose the original version to compare**

Click in the `original version` field and choose the first version that you want to compare, for example:

{% hint style="info" %}
All existing versions are available for selection.
{% endhint %}
{% endstep %}

{% step %}
**Choose the comparison version**

Click in the `comparison version` field and choose the version that you want to use for comparison, for example:

{% endstep %}

{% step %}
**Review comparison information**

Comparison information is displayed in dual panels, so you can scroll to view differences:

{% hint style="info" %}
Look for marker bars down the edge of the `comparison version` panel. These show where differences are noted - click on a marker to jump to that point in the comparison:
