# 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

{% 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:  &#x20;

**Choose the comparison version**

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

**Review comparison information**

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

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:
