Move existing Windows 7 or 10 installation to new computer?

I have a Windows 7 64-bit installation on my current PC, and I want to move it to a new PC .. I do NOT have a problem with licensing, as the new system already has its own new Windows 7 license, which I intend to use.

I want to use my existing installation, because it has 3 years worth of installed office related software development software, which installing again could take weeks !

I'm assuming that I can use Windows 7's Backup and Restore feature to backup a system image to a network location, then restore that network stored system image on the new PC ?

Again, like I said, I don't have a WIndows 7 licensing issue, as both machines are corporate provided and come with their own licences.

Can't you just 'dd' one disk to the other in your existing PC (so you have the original to fallback to) -> insert the "copy" disk in new PC -> boot the new machine -> sysprep /generalize /reboot -> Install drivers as necessary -> activate Windows with new machine key...? You shouldn't need to buy any software.. a LiveCD should do...? – Kinnectus – 2014-07-06T11:26:48.397

3The Windows 7 Back and Restore feature will NOT transfer your applications you would have to reinstall those if you used that option. Acronis True Image and other alternatives has the ability to migrate an image to different hardware. You can do it yourself by putting Windows into a mode, but its not easy, and might simply be worth the small amount of money to do it with speciailized software. – Ramhound – 2013-09-13T12:33:04.187

Is the hardware the same or different? You may have some driver issues if you just try to do a clone from one hard drive to another, though Win 7 is far better than previous OSes at sorting out hardware changes. – trpt4him – 2013-09-13T12:46:41.563

I don't mind the occasional driver issues, as long as my software environments run out of the box. @Ramhound, which software are you specifically suggesting which has better migration capabilities ? Acronis True Image ? Will it move the entire Windows 7 installation, including all installed stuff and files, without causing any boot/incompatiblity problems on destination PC ? – Ahmad – 2013-09-13T12:50:15.217

Also, the hardware is different between the two PCs .. Different motherboard, different CPU (both are Intel though), more RAM, etc .. – Ahmad – 2013-09-13T12:51:01.750

2@Ahmad - Acronis True Image 2014 Premium does have the ability to migrate your Windows installation from PC A to PC B where PC B has entirely different hardware. This of course requires two licenses and for you to manually change the license and reactivate the installation. There are other alternatives that do this, in exactly the same way, Acronis does it. Like I said you can place Windows into a migration mode, duplicate the HDD, and Windows would install the required drivers to boot. – Ramhound – 2013-09-13T13:35:23.560

Short answer: you have to run sysprep on your old PC, shut it down and move the drive to the new PC.

Long answer: Sysprep is one way only and it strips Windows from all hardware drivers, once you run it, you'd have to install drivers on your old PC as well. You need to create a backup of your Windows in case something will go wrong.

Use the following procedure if you have a spare new drive:

Clone old drive to the new disk, connected via USB to old PC (use gparted or clonezilla live CD)
Swap disks and boot old PC from new drive
Ensure you have the product key as Windows 10 may require it after booting in new PC
Run sysprep on old PC with new drive, shutdown old PC
Put the new drive in new PC, boot and see how and if it works. This way you will still have an untouched old drive that you can still use.

1This is the easiest way to move an existing W7 installation i have ever found, sysprep is built into W7 also, it can be found in C:\Windows\System32\sysprep – Moab – 2015-05-19T23:09:05.170

I ran sysprep /generalize but I can't get the drive to boot on the new machine; the new drive boots on the old machine but not the new one, not even in safe mode. The processor is different and I'm sure it doesn't have the driver for it. How do I fix it? – bgmCoder – 2016-03-06T20:21:07.953

@bgmCoder Does windows start booting and then crashes or boot sequence not even starting? – Alec Istomin – 2016-03-09T04:10:51.283

@AlecIstomin Ah, I ended up doing a fresh install and moving everything manually; took me all night. But yes, windows would start booting and then crash. – bgmCoder – 2016-03-09T16:44:30.443

It's easy: use Pen Drive Linux and Ubuntu to perform a bitwise clone to the new storage device. (Be sure the new storage device is at least as large as the old one.) Disk cloning instructions are here.

Afterwards, if Windows won't boot, you can download the critical chipset drivers and install them from the Windows install media's Recovery Console with DISM. This is more an issue for Windows 7, as Windows 10 is pretty good here. Once Windows is booting, install any remaining drivers and you should be good to go.

Connect the new PC's hard disk to your old PC and mirror the old hard disk using GParted. I think it even allows mirroring over networks, but I don't have any experience doing that. Once done, move the hard disk back to your new PC. The system most likely won't boot up properly, so use Windows 7's restore console. It should be able to fix the issues during two or three attempts.

Important: Don't try to mirror your old hard disk using tools such as Norton Ghost. I've done this in the past and it will modify your old hard disk trying to add bootup entries for the new disk (which never worked for me; i.e. I've been sitting there with an unbootable source disk). So it didn't even do a proper backup.

I don't know... if you were trying to grab an image from a disk and ended up messing up that disk, I think you may have done something wrong. I've used Ghost in the past and have never seen it modify the source image like that. – trpt4him – 2013-09-13T12:46:12.170

Just used it's "mirror disk" function or whatever it's been called. It tried to add the new disk to the old disk's boot manager for whatever reason. – Mario – 2013-09-14T16:02:49.947

None of these descriptions sound like they'll move an existing installation to a new machine intact. Moving to a new hard drive doesn't count. – I say Reinstate Monica – 2018-01-05T00:49:06.977
