IMPORTANT : The issues that are discussed in this article and in the
linked articles are the most common problems and limitations that you
may encounter when you try to restore a backup copy to different
hardware. Other issues can also appear because of the variations in
software and hardware configurations. You may be able to resolve any
of these issues by troubleshooting the specific problems that occur,
but compatibility issues may limit the success of the restore of a
backup to dissimilar hardware.
Samenvatting
This article describes how to move an installation of Windows XP to
new, upgraded, or just different hardware. By using this information,
you can:
Migrate a working Windows XP operating system and your installed
programs to a different or more powerful computer in minimal downtime.
Replace a small system/boot disk drive with a larger system/boot disk
drive.
Restore a Windows backup from a malfunctioning computer to a different
computer for disaster recovery purposes.
Meer informatie
Windows Backup (Ntbackup.exe) can handle differences in hardware
configuration information between computers and maintain critical
registry entries that are unique to the computer to which you are
migrating information. This capability means that you can migrate to
new hardware by performing a full backup of the source computer and
then restoring the backup over a fresh installation of Windows XP on
the destination computer.
Ntbackup.exe handles restore operations in the registry by first
querying the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\KeysNotToRestore
This registry key indicates to Ntbackup.exe that certain registry keys
under the HKEY_LOCAL_MACHINE\SYSTEM key should not be overwritten when
files are restored.
An entry that ends with a backslash (\) indicates that a key is
protected and that any keys or values under that key should not be
restored. If the entry ends with a backslash and an asterisk (\*), all
subkeys are "merged." In this situation, "merged" means comparing the
start values of the keys in the backup set with the start values that
exist in the current registry, to determine the correct key to
restore.
If the value of the key on the backup set has a lower start value, the
backup key takes precedence. If the value of the key in the current
registry has a lower start value, the current key takes precedence.
This process ensures that all services and devices start correctly
after a "system state" restoration, even on dissimilar hardware.
For example: If the value of the following key on the backup set has a
lower start value, the backup key takes precedence:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp
If the value of the same key in the current registry has a lower start
value than the key you want to restore, the current key takes
precedence.

After the computer successfully restarts, Windows Plug and Play takes
care of any minor differences in hardware configuration.
The Factors to Consider Before You Use This Procedure
Drive Letters and the %SystemRoot% Folder
For a complete migration to work correctly, the %SystemRoot% folder
(the Windows folder in Windows XP) and the drive letters for any
(target) volumes that contain a system-state component must be the
same on both the source computer and the destination computer. This
means that if the source computer has, for example, Windows XP
Professional installed in the C:\Windows folder and has Active
Directory (NTDS) and SYSVOL on separate drives, drive D and drive E
respectively, the destination computer must have Windows XP
pre-installed in a C:\Windows folder and contain drives D and E before
the restore operation can succeed.
Hardware Abstraction Layer (HAL)
The HALs on both of the computers should be the same. This means that
the source and destination computers should be using the same HAL type
to achieve favorable results. Although this is not a requirement, the
computer may not perform migration properly if the HALs do not match.
To determine the type of HAL that you are using on each computer:
Click Start , click Control Panel , and then double-click System .
On the Hardware tab, click Device Manager , and then view the listing
under Computer . Possible values for the system description and the
associated HAL include:
ACPI Multiprocessor PC = Halmacpi.dll
ACPI Uniprocessor PC = Halaacpi.dll
Advanced Configuration and Power Interface (ACPI) PC = Halacpi.dll
MPS Multiprocessor PC = Halmps.dll
MPS Uniprocessor PC = Halapic.dll
Standard PC = Hal.dll
Compaq SystemPro Multiprocessor or 100% Compatible = Halsp.dll
The Windows\Repair Folder
The Windows\Repair folder that contains your source computer hardware
and software configuration files and the Setup.log file may not be
valid for the new hardware on the destination computer to which you
restored them. You should perform an in-place upgrade on the
destination computer to update these files so that you can make the
appropriate repairs in the future if necessary.
NTFS Volumes
You may need to start special filter drivers before you can restore
files that contain reparse points to NTFS volumes. This means that
before you can restore these types of files, you need to restart the
computer after you restore the operating system. Examples of these
types of files include Remote Installation Services (RIS) images that
rely on Single Instance Storage (SIS), Remote Storage Server (RSS)
files that you are restoring to managed volumes, or other third-party
services that use reparse points and require filter drivers.
The Procedure for Moving a Windows Installation
On the destination computer, perform a new installation of Windows,
using the product type that matches that of the source computer.
Ensure that the drive letter and %SystemRoot% folder names match those
on the source computer.
Using Disk Management, create, format, and assign drive letters to any
additional volumes that may be required to hold a system-state
component (for example, SYSVOL, Active Directory, or Active Directory
Log files). Ensure that all drive letters match those on the source
computer. For additional information about drive letter assignments,,

Base: On the source computer, log on as Administrator, and then stop
all the non-essential services that you normally stop before
performing a backup.

If the computer does not restart after restoration because of HAL
mismatches, you can start from the Windows installation disk to
perform an in-place installation or repair. This type of repair occurs
after you accept the licensing agreement, and Setup searches for
previous versions to repair. When the installation that is damaged or
needs repair is found, press R to repair the selected installation.
Setup re-enumerates your computer's hardware (including the HAL) and
performs an in-place upgrade while maintaining your programs and user
settings. This also refreshes the %SystemRoot%\Repair folder with
accurate information that you can use for normal repairs.
If the computer does restart after the restoration, log on as
Administrator and initiate an in-place upgrade by running Winnt32.exe
from the i386 folder on the Windows CD-ROM. This refreshes the
Setup.log and registry files in the %SystemRoot%\Repair folder, and
ensures that the proper HAL is in use.
Note that in Microsoft Windows NT 4.0, user profiles are stored as a
subfolder of the %SystemRoot%\Profiles folder. In Windows XP, if the
installation is an upgrade, the existing profile path continues to be
used. In new Windows XP installations, a Documents and Settings folder
is created on the same volume as the Windows XP installation, to hold
user profiles. If the original system was an upgrade from Windows NT,
the original profiles will be used after the restore. However, if an
in-place upgrade is performed, you may need to change the profiles'
path in the registry back to %SystemRoot%\Profiles by modifying the
keys under the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\ProfileList
For additional information about drive letter assignments,, click the

Base: After the upgrade is finished and you are certain that
everything works, you can remove the source (original) computer from
the network and connect the destination (new) computer in its place.
NOTE : The difference between the time of the backup and the time of
the restoration to the new computer may affect the machine account on
the domain controller. You may have to join a workgroup first, and
then rejoin the domain.
