Hey Bram!
My name is Ravi, and I am an independent advisor. I am happy to help you. :)
Mirroring a laptop to another laptop isn't like mirroring a phone. Getting everything from one laptop to another requires a few steps:
1). Backup the data from your old laptop.
2). Transfer the data to your new laptop.
For users and other settings, you need to add them manually because every laptop has a different configuration. And both might have different versions of Windows.
There are different ways to transfer the data.
1). Copy everything into an external USB or hard drive. Paste the data to your new laptop.
2). Use cloud storage to sync the data and then sign into your new laptop using the same account. At present, the most stable and safe way is to use Onedrive to back up your old computer's data and files, and then use Onedrive to sync to your new computer. https://www.microsoft.com/en-us/windows/transfe...
