I have been preparing for a similar scenario with a Win7pro64 machine.
I also have some permanent licenses locked to that machine. Some vendors may not honor those contracts and have/will shut down the activation servers.
Examples:
Microsoft Windows 7
Microsoft Office 2013
Adobe Photoshop Elements 11
Adobe Premiere Elements 11
Adobe Lightroom 6
(Old Eagle 7 Pro licensing is a nice exception)
I bought spare parts, i.e. CPU (i7-4770K), RAM, mainboard, PSU to prepare for the worst, but also as single spare items (most likely scenario).
Copying the SSD is simple in the case of new Samsung SSD's, which come with a migration tool (I would recommend doing a backup of your SSD before further tests, using a spare PC with a couple of extra SATA-connectors.)
If the migration tool is not an option, Linux' 'dd' may be.
When I insert a clone of the system disk (Samsung EVO 860 pro), Windows will boot up. However it will detect the different Mobo or CPU. I haven't tried switching CPU's. The question that I can't answer atm is, which of those programs will work on the new board, without re-activation.
It may be helpful to figure out if switching mainbords, while keeping the CPU, will keep your the licenses.
At any rate, should I have to switch boards and CPU and run into license related problems, I wouldn't hesitate to procure unlocked specimens of the versions for which I have bought permanent licenses.
Suggestion for the TO's concrete questions:
- get a spare SSD and copy the original disk. This will give pointers regarding that item's state
- plug the spare into the new laptop and try to boot, while disconnected from the internet. If the system boots, you will have a several days-long period of grace, where you can check out the actual situation
- proceed from there, maybe all you need is a reactivation of Windows 7. Worst case would be the requirement to call Microsoft and explain the situation to an operator
At any rate - good luck. Looking forward to your findings.
