Previously I covered how to use the VCSA Installer to do a scripted upgrade and then I covered Patching the vCenter Server Appliance (VCSA) using the REST API - Part 1 (Postman Collection) However, after learning recently how to call API’s from Powershell I thought to myself, why not write a Powershell Module for this?

Introduction

Using tools such as Postman can make it utilizing API’s a bit easier, but you still need to be familiar with a separate tool or UI. I was able to develop my own version and build my first Powershell Module that you can use to patch the VCSA in a simple method. Some of the function names below may not be 100% exact and this is due to the accepted verbs for Powershell. If you have further recommendations I would be happy to entertain changing the Powershell verbage.
