# Manual Upgrade

The NextSeq 500/550 Integration v2.5.0 integration package requires the NextSeq 500/550 v1.3 workflow available from IPP v2.10. If you do not want to upgrade through the IPP, you can manually upgrade the workflow configuration from NextSeq 500/550 v1.2 workflow to v1.3 workflow by following instructions in this guide to generate samplesheet compatible with LRM v4.0.

## Generate NextSeq 500/550 Samplesheet Compatible with LRM v4.0

To support the generation of LRM v4.0-compatible samplesheet, you must modify the **Denature and Dilute** step, and replacement of template files.

### Modify Denature and Dilute Step

**Automation**

1. From Configuration, select the Automation tab.
2. Rename the **Generate bcl2fastq2 NextSeq Samplesheet** automation to **Generate NextSeq Samplesheet**.

{% hint style="info" %}
The default command line for the automation remains unchanged.
{% endhint %}

**Master Step Fields**

1. From Configuration, select the Custom Fields tab.
2. Select the **Denature and Dilute** Master Step.
3. Add the following master step fields:

   | **Field Name**       | **Field Type** | **Field Constraints/Options** | **Preset Values/Additional Options and Drop-Down Items**                                                     |
