In-place upgrade failed Server 2022 to Server 2025

Question

I've been working on in-place upgrades of Serve 2022 to Server 2025, and I have one server that fails to upgrade after a lengthy upgrade process. I've run the DISM /cleanup (Windows Server 2012 R2 upgrade to Windows Server 2019 fails - Microsoft Q&A), and even deployed both the Nov 2024 and Dec 24 ISOs, yet they all fail to upgrade this one server.

See attached setup*.log files.

Where to look to get this pesky server upgraded?? Thank you.

Answer 1

Hi if you installed third party antivirus then turned it off and also close all the background apps then start the windows server 2025 setup. I hope it will fix your issue.

Answer 2

Hello,

Thank you for posting in Microsoft Community forum.

Based on the description, I understand your question is related to Server 2025.

Please check if your machine meets the minimum requirements of installing Server 2025:

1. CPU

• 1.4 GHz 64-bit processor
• Compatible with x64 instruction set
• Support for NX and DEP
• Support for CMPXCHG16b, LAHF/SAHF, and PrefetchW instructions
• Support for Second Level Address Translation (EPT or NPT)
• Support for the SSE4.2 (Streaming SIMD Extensions 4.2) instruction set
• Support for the POPCNT instruction

You can utilize Coreinfo, which is a tool included in Windows Sysinternals, to verify the capabilities of your CPU.

2. RAM

• 512 MB for Server Core
• 2 GB for Server with Desktop Experience, 4 GB recommended
• ECC (Error Correcting Code) type or similar technology for physical host deployments

3. Storage

• 32 GB of space

4. Network

• An Ethernet adapter that can achieve a throughput of at least 1 gigabit per second
• Compliant with the PCI Express architecture specification

A network adapter that supports network debugging (KDNet) is useful, but not a minimum requirement.

A network adapter that supports the Pre-boot Execution Environment (PXE) is useful, but not a minimum requirement.

5. There are other hardware requirements to consider depending on your scenario:

• DVD drive (if you intend to install the operating system from DVD media)

The following items are only required for certain features:

• UEFI 2.3.1c-based system and firmware that supports secure boot
• Trusted Platform Module (TPM)
• Graphics device and monitor capable of Super VGA (1024 x 768) or higher-resolution
• Keyboard and Microsoft mouse (or other compatible pointing device)
• Internet access (fees might apply)

Have a nice day. 

Best Regards,

Molly

Answer 3

I satisfy the server requirements. I have other servers that upgraded to 2025 no issue that used the same VM template as this server that errors on the upgrade.

Not sure where to go to get this upgraded.

Answer 4

AV disabled, but still failing on the upgrade.

Answer 5

Hello,

May I know what kind of VM it is? Is it an Azure VM/Hyper-v/VMWare?

Best regards,

Molly
