Acronis True Image 2015

First of all, if your OS is Windows 7 OEM, which pretty much every pre-installed OS is, you won't be able to move an OS from one PC to the other, you'll get activation issues, unless you live in the EU or Switzerland, where you can usually reactivate it by phone.

If it isn't OEM, then you'll have to check whether there is a Restore to different hardware option (or similar). This will remove your old drivers and you can usually also inject the drivers for your new hardware. But I don't know whether acronis has that option included, or if you need an optional addon for that. Paragon products have that included in their products, at least those that aren't free...

But even if there is such an option, you will also have to make sure that there are drivers available for Windows 7 for your hardware.

Both of them are Dell's.  Acronis  claims that you go fromA  to B with any computer.

As I said, three times I've backed it up and then restored with a new computer. Is there anything else that I am forgot?

Thanks!
