However, according to Microsoft, such backups are only guaranteed to restore the same physical machine, or different physical computers with the same hardware (same make, model and configuration).
Although some articles indicate that you can do AD forest recovery of different machines with a full server backup, it is highly unlikely to go wrong in practical applications. Therefore:
In the following article, I will illustrate both the 2 methods below to help you migrate Windows Server 2012 R2.

The target computer should have the same boot mode (Legacy/UEFI) as the source computer. Otherwise, you will likely receive errors during restoration.
You can boot into BIOS to ensure the boot mode is the same, or manually reconfigure it. If you change the boot mode, remember to convert disk into the corresponding partition style.
