This is probably the result of setting MODULES=dep in 
/etc/initramfs.conf. When changing hardware I'd recommend changing that 
to MODULES=most and then running "update-initramfs -k all -u" to 
regenerate the initramfs with the additional modules. It is possible to 
fix this with a rescue image if one forgets.

I've installed debian on a lot of machines with a lot of NVMe devices, 
and never had an issue. The hardware is pretty standardized, and the 
only thing I can think of which might cause an issue would be something 
like an HMB drive with an older linux that predates support for HMB, or 
a PCIe topology problem (unlikely in consumer hardware). In general I 
would expect normal NVMe to just work. I can think of additional failure 
modes causing inability to boot on older hardware, but the kernel should 
still see the drive.

Apart from the need for the nvme driver to be in the initrd (just as 
you'd need an ata, scsi, etc module for those devices) it should be 
possible to migrate fairly easily. NVMe works just like SATA SSD from 
the partition level up (i.e., the stuff you'd dd). One somewhat 
different thing is the concept of NVMe namespaces: your drive will be 
/dev/nvme0, but you'll probably be using /dev/nvme0n1 except for device 
management. Partitions then look like /dev/nvme0n1p1. It's unlikely that 
you'd be creating/using additional namespaces apart from the first 
(default) one.
