How to Plan an In-Place Upgrade to Windows Server 2025
Applies to: migrations involving Windows Server 2019, 2022 and 2025.
An in-place upgrade preserves roles, applications and data, but only on a supported upgrade path and after vendor compatibility review.
Migration requires a tested rollback and application-owner acceptance. Visit networkmanager.info for managed Windows VPS services.
Prerequisites
- Verify Microsoft-supported source edition and path.
- Confirm every application supports Windows Server 2025.
- Take full and application-aware backups.
- Provide console access and matching installation media.
Procedure
Step 1: Inventory server
Capture roles, edition, build, drivers and applications.
Get-ComputerInfo | Select WindowsProductName,OsBuildNumber,WindowsInstallationType
Get-WindowsFeature | Where InstallState -Eq 'Installed'Step 2: Run health checks
Resolve disk, servicing and event errors.
Step 3: Update firmware and applications
Use vendor-supported versions before OS change.
Step 4: Test clone
Perform the upgrade on an isolated representative copy.
Step 5: Start setup
Mount authorized media and choose Keep files, settings and applications only when offered by the supported path.
Step 6: Validate after restart
Patch, verify roles and execute application acceptance.
Verification
Compare inventory, services and application transactions with baseline.
Get-ComputerInfo | Select WindowsProductName,OsBuildNumber
Get-WindowsFeature | Where InstallState -Eq 'Installed'Rollback
Use the setup rollback only while available; otherwise restore the tested full-system backup or return service to the previous server.
Operational notes
Domain controllers, clusters and application servers have role-specific upgrade sequences.
