Okay anon, I haven't had to do something like this for a long time so maybe some of you can help out.
>Has Win10 install on ancient but reliable as fuck Samsung 840 PRO SATA SSD 2.5"
>Selling CPU/Mobo/RAM of the same PC, so I need to basically disassemble the core of that PC and pack it up for sale.
The old PC with Win10 is a long serving Intel X99 mobo HEDT platform (5960X 8c/16t CPU + 16GB DDR4 ); really kind of annoyed neither they nor Threadripper really exist in the same way they used to for mixed enthusiast use, but I digress. I also have the new "replacement" PC built which is an AMD X670E mobo AM5 platform (7950X3D CPU + 64GB DDR5).

What is the chance I could connect the old SSD to the new PC and just boot up Win10 from there without it completely shitting the bed? The new PC for the moment has one drive with a Win11 install I was using for stability testing, so it should potentially see the Win10 and give an option to boot into it. The question is the Win10 install having a massive shitfit being on a completely different CPU, Mobo, RAM etc? I know that I can likely just boot into Win11 (or Linux for that matter) and just read the Win10 drive's files and sort things out, back up from there but that's a fuckload more time and effort to get right than being able to just boot Win10 and use the thing in the interim.

I know in the older days (ie Win7 and certainly prior) trying to do this would mean a likely clusterfuck, but some have said these days its not that much of an issue (with the exception of likely having to re-register Windows10 given the new mobo etc)?
