Cloning Requirements

Cloning Requires the Same Base Operating System

See also Basic Requirements.

When cloning Active Directory between two computers the source computer must run the same base operating system as the destination computer. If (for example) the source computer is running an edition of Windows Server 2019 Version 1809 then the destination computer must also run an edition of Windows Server 2019 Version 1809.

You can move Active Directory to a different edition of Windows Server if the base operating system is the same. For example you can move AD from Windows Server 2016 Essentials to Windows Server 2016 Standard Edition. Or from Windows Server 2019 Standard Edition to Windows Server 2019 Datacenter Edition. See the Supported OS Clone Combinations.

Windows Server 2012 (non-R2) to Windows Server 2012 R2

You cannot use U-Move to clone AD from Windows Server 2012 (non-R2) to Windows Server 2012 R2. This is because the base operating systems are different (Windows 8 versus Windows 8.1).

Windows Server 2008 (non-R2) to Windows Server 2008 R2

You cannot use U-Move to clone AD from Windows Server 2008 (non-R2) to Windows Server 2008 R2. This is because the base operating systems are different (Vista versus Windows 7).

To move AD from a non-R2 operating system to an R2 operating system you must do a swing migration.

Cloning from 32-bit to 64-bit

U-Move can clone Active Directory from 32-bit Windows Server 2008 (x86) to 64-bit Windows Server 2008 (x64).
