In-Place Upgrade Windows Server 2019 to 2022: Complete Sysadmin Guide (Zero Data Loss)
Performing an in-place upgrade from Windows Server 2019 to Windows Server 2022 enables system administrators to modernize their infrastructure with advanced multi-layer security (Secured-core server), native TLS 1.3 encryption, and upgraded hybrid cloud capabilities without wiping local disk storage or rebuilding domain configurations. In-place upgrades preserve Active Directory Domain Services (AD DS), Hyper-V virtual switches, DHCP scopes, file shares, and IIS bindings. To ensure a 100% successful upgrade with zero downtime or data loss, administrators must verify hardware prerequisites, take a full bare-metal or VM snapshot, run Windows Server Setup using official media, and activate the server using a genuine Windows Server 2022 Standard license.

4. Step 3: Post-Upgrade Verification & Driver Health
After the server finishes rebooting into Windows Server 2022, verify service health in PowerShell (Admin):
[System.Environment]::OSVersion.Version
Get-Service | Where-Object { $_.StartType -eq ‘Automatic’ -and $_.Status -ne ‘Running’ }
5. Step 4: Activate Windows Server 2022 with Genuine Key
