SUMMARY
In-place upgrade from Windows 11 Education 23H2 (Build 22631.6276) to 25H2 (Build 26200.6584) consistently fails during SAFE_OS / MIGRATE_DATA phase with error 0x8007042B – 0x2000D.
Panther logs show critical failure in Microsoft-Windows-TPM-Driver-WMI (CCSIAgent) migration unit with message: "Source migration unit is not supported on the destination machine and it will not be restored"
Looking for confirmation if this is a known 25H2 issue or if there's a supported workaround.
ENVIRONMENT
OS: Windows 11 Education 23H2, Build 22631.6276
Target: Windows 11 25H2, Build 26200.6584
Hardware: Gigabyte Z690 AORUS PRO, WD_BLACK SN770 NVMe, Intel PTT (TPM 2.0), Secure Boot enabled
BitLocker: Off (fully decrypted)
Upgrade methods attempted:
- Windows Update feature enablement
- Windows 11 Installation Assistant
- Official 25H2 ISO mounted locally via setup.exe
ERROR DETAILS
Setup reaches SAFE_OS phase, then fails during MIGRATE_DATA and rolls back.
From setuperr.log and setupact.log:
V2VArbitrate: Source migration unit System Microsoft-Windows-TPM-Driver-WMI (CCSIAgent) is not supported on the destination machine and it will not be restored
V2VArbitrate: Source migration unit is critical, arbitration will fail
V2V Arbitration failed. Last error: 0x00000032
pSPExecuteApply: Apply operation failed. Error: 0x0000002C
ExecuteOperations: Failed execution phase Safe OS. Error: 0x8007042B
Secondary errors (sometimes present):
DirectoryServices-ADAM-Client adammigrate.dll plugin fails with 0x80070002 during IPostApply ApplySuccess, but these are often logged as "ignore" - the actual rollback trigger is always the TPM-Driver-WMI critical migration failure.
TROUBLESHOOTING COMPLETED
System Health:
- sfc /scannow - clean
- DISM RestoreHealth - clean
- chkdsk - no errors
- WD Dashboard - drive healthy
TPM and Drivers:
- TPM 2.0 device present (ACPI MSFT0101)
- Using Microsoft inbox TPM driver only
- Removed all OEM TPM drivers via pnputil
- Removed legacy problematic drivers (Intel CougarPoint USB)
Security Software:
- McAfee WebAdvisor uninstalled
- Kaspersky completely removed (standard uninstall + kavremover in Safe Mode)
- Only Windows Defender active
Services:
- DiagTrack service set to Manual and Running
Cleanup:
- Deleted all upgrade folders (WINDOWS.~BT, GetCurrent, WINDOWS.~WS, SoftwareDistribution Download)
- DISM StartComponentCleanup ResetBase completed
- Re-ran RestoreHealth and sfc after cleanup
Media Verification:
- Both 23H2 and 25H2 official ISOs SHA-256 verified
- Mounted locally, no third-party tools
- Tried with Dynamic Update enabled and disabled
Compatibility Testing:
- setup.exe /Compat ScanOnly /DynamicUpdate Disable completes WITHOUT errors
- Full upgrade with same parameters FAILS in SAFE_OS with TPM-Driver-WMI error
ADAM Feature:
- DirectoryServices-ADAM-Client currently disabled in DISM
- Tried enable-disable cycle with reboots
- ADAM errors sometimes disappear but TPM-Driver-WMI error persists
Component Investigation:
- DISM Get-Packages shows NO Microsoft-Windows-TPM-Driver-WMI package
- No TPM-Driver-WMI cab found in 23H2 ISO
- Component exists in WinSxS but not as installable package
- Cannot repair via DISM Add-Package (no package available)
CURRENT STATUS
Compatibility scan: PASSES
Full upgrade: FAILS at same point every time with TPM-Driver-WMI critical migration error
The system appears healthy by all diagnostic measures, but the upgrade process cannot migrate this specific component.
QUESTIONS
- Is Microsoft-Windows-TPM-Driver-WMI (CCSIAgent) migration failure a known issue in Windows 11 25H2 upgrades, particularly for Education edition?
- Is there a supported method to repair or reset the TPM-Driver-WMI migration unit on the source system when no standalone package exists?
- What is the recommended resolution path:
- In-place repair install of 23H2 first, then retry 25H2 upgrade?
- Direct clean install of 25H2?
- Wait for updated 25H2 media or cumulative update?
- Are there known differences between Consumer and Education 25H2 media regarding TPM-Driver-WMI migration manifests?
Any official guidance would be appreciated before proceeding with a clean install.
Thank you.
