Upgrading a NVME Driver to bigger drive
Before migrating to another NVME make sure the following is run from the Windows CMD prompt as admin
sc.exe config stornvme start= boot
The reason to do this is some NVME SSD's are not really NVME! they are SATA controllers. So by default the OS will not be running the NVME drivers and after you bootup with the new NVME the boot device not found issue will occur.
