# Upgrading a clustered Pathfinder Server system

## Scope

This HelpDoc goes over the process of performing a software update to Pathfinder Server, when you have dual servers running. Also known as a clustered Pathfinder Server system

## Description

In most cases, upgrading a clustered system can be done without creating disruption. We can upgrade one server at a time, letting the system failover. This guide is best suited for those that have existing Pathfinder 5.X and want to update to the last 5.X version released

If your system is not clustered - just follow steps 1-6 to complete an upgrade for a standalone system

## Preparation

- On​ ​both​ ​servers​ ​make​ ​a​ backup ​copy​ ​of​ ​the​ ​Program​ ​Files​ ​directory​ ​for​ ​Pathfinder​ ​Server
- On​ ​both​ ​servers,​ ​go​ ​into​ ​Pathfinder​ ​Server,​ ​File​ ​Menu​ ​and​ ​select​ ​Licensing.​ ​Note​ down ​the Request​ ​Code​ ​and​ ​License​ ​Key​ ​for​ ​both servers
- Note​ ​the​ ​current​ ​running​ ​version​ ​of​ ​Pathfinder​ ​Server​ ​before​ ​attempting​ ​the​ ​upgrade. You can find this by going to Help, About Pathfinder PC in the Pathfinder Server application. The Version number is located at the top of the splash logo that appears
