# Comparing process flow versions
## Introduction
With the ability to [deploy](/product-documentation/virtual-environments/implementing-virtual-environments/deploying-a-single-process-flow-to-a-virtual-environment.md) different versions of a process flow to multiple virtual environments, it can be useful to compare two flows and highlight the differences between them. You can do this with the `compare flows` option.
## Using the compare flows option
{% stepper %}
{% step %}
**Access the required process flow**
[Access the first process flow](/product-documentation/process-flows/accessing-your-process-flows.md) with versions that you want to compare.
{% endstep %}
{% step %}
**Open process flow settings**
Select the `settings` icon from the actions bar:
{% endstep %}
{% step %}
**Select compare versions**
Click the `compare versions` button:
{% endstep %}
{% step %}
**Select two versions for comparison**
Select the `original` version to be compared - for example:
...then choose a `comparison` version - for example:
{% endstep %}
{% step %}
**Review comparison information**
Comparison output is displayed in left and right panels, with highlighted differences - for example:
{% hint style="info" %}
To search within this output, click in the required left/right panel and then press CTRL+F to display search options:\

{% endhint %}
{% endstep %}
{% endstepper %}
