📋 Step-by-Step Upgrade Process

Step 1: Download Windows Server 2022 Installation Media

• Download the Windows Server 2022 ISO from:

Step 2: Mount the ISO and Run Setup

1. Copy the ISO file to your server’s desktop (optional but recommended)
2. Right-click the ISO → Mount (or insert DVD if using physical media)
3. Open File Explorer, double-click the mounted drive
4. Run setup.exe as Administrator

Step 3: Windows Setup Wizard

1. On the Windows Setup page, click “Download and install updates (recommended)”

Step 4: Select Installation Type

1. On the “Which type of installation do you want?” screen, choose:

   • This is the in-place upgrade option that keeps everything

Step 5: Select Operating System Image

1. On the “Select Image” screen, choose the matching edition:
   • Windows Server 2022 Standard (Desktop Experience) OR
   • Windows Server 2022 Datacenter (Desktop Experience)

Step 9: Log In After Upgrade

1. When finished, log in with the same credentials as your Server 2019

🚨 Important Notes

Consideration	Detail
Have a backup UPS running	Don’t want a glitch or power outage to corrupt upgrade
Domain Controller	If this is a DC, test thoroughly. Microsoft recommends clean install for DCs
Rolling back	Once upgraded, you cannot roll back to 2019. Your backup is your only rollback option
Best practice	Microsoft recommends clean install for production servers, but in-place upgrade is supported
Remote upgrade	You can do this via iDRAC, RDP, or local console without disconnection
