Hi,
Veeam won’t be able to perform an OS-Upgrade for you, and it should be pointed out that Upgrading Windows Server 2012 Foundation is not supported, in any scenarios, by Microsoft (Link:https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-foundation/jj679892(v=ws.11)#upgrading-windows-server2012-foundation) though I believe from the way you’ve written your previous comment you already knew this, I’m just calling this out to be clear.
The questions that need to be asked at this point are what you need to restore.
Windows Server 2012 Foundation had many products installed/licensed as one image. Veeam can backup your data, however you’ll have the following key issues:
- ACL - Without a domain, permissions can’t be preserved between servers, due to a lack of common domain.
- Windows Server 2012 Foundation is NOT permitted to be used as a virtual machine, I don’t know that it will block you from running as a VM, but it certainly is in violation of your Microsoft Licensing agreement.
- Applications, whilst they can be processed by Veeam, will not be able to be directly restored to a new server, some exceptions exist, such as SQL Server database instances, but again, due to a lack of domain, ACLs within SQL Server won’t be preserved.
You’ll need to do this the hard way, you’ll need to catalog your applications, create a new virtual machine to install them on, and see how these applications get migrated, by the appropriate vendor. Veeam can certainly help if there are file shares, or in general, files that need to be backed up. You could for example perform an agent level backup, and then perform an export of the disk to a VMDK, to attach to your new VM, this would give you a copy of the data within the OS, to attach to any application installations as appropriate, but any file shares & permissions would still require being newly created.
I hope this helps as a starting place.
