Download

I’ve downloaded the ISO from the Download Center

Pending Reboot

It’s best to check for Pending Reboot, before the installation.

.\Check-PendingReboot.ps1

Installation

I’ve copied the ISO to the Exchange Server and mounted it. Then started the setup.exe

Reboot

I always reboot the Server after installation to make sure everything is workin perfectly

.\Check-PendingReboot.ps1

Check Version

Check the Exchange Server Version

Get-Command Exsetup.exe | ForEach-Object {$_.FileVersionInfo}

Check EMS and EAC

Let’s check the Exchange Management Shell (EMS)

Let’s check the Exchange Admin Center (EAC)

Healthchecker

After Updating Exchange you should always run HealthChecker

Run HealthChecker to update Version

.\HealthChecker.ps1

Run HealthChecker and check the Warnings and Errors

.\HealthChecker.ps1

Summary

So far everything works fine and the Update is much more boring than we all expected 😊
