If your system comes with a single M.2 PCIe slot and drive, and you purchase a new Crucial PCIe drive you wish to replace it with, there are few options you have to get your data transferred from one drive to another.
Cloning: You can do a direct clone to copy the information from your current PCIe M.2 drive to a new Crucial one. To accomplish this, you will need to purchase a USB to PCIe M.2 adapter cable. With the new Crucial SSD connected through one of these adapters you can simply download and install Acronis True Image for Crucial, then follow our steps to clone to your drive. Once the clone is finished all you need to do is shut system down, swap your old SSD with your new one, and verify Windows loads correctly.
For instructions on installing an M.2 we have this document with basic guidelines, you however will want to find the manual provided by your system manufacturer for more specific steps on your unique model.
Image backup restore: With any newer version Windows, you can create an image backup using their built in utility to a 3rd backup hard drive or flash drive of sufficient size. Then with a Windows recovery media you can restore that image directly onto your newly installed M.2 PCIe SSD. Be sure to contact Microsoft if you have any problems using their backup and recovery utilities. With the image restored to your new PCIe SSD, you can now test Windows to make sure everything is running correctly.
