From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Funnily enough, when I upgraded from a SATA SSD to an NVME, I didn't have to reinstall anything. Instead I just moved the LVM LVs to the NVME and rewrote the boot config. Just booted up from the existing installation without having to install anything.
Of course, tune2fs reports the right age for the filesystem:

# tune2fs -l /dev/mapper/VolGroupSSD-ssdvol | grep created
Filesystem created:       Thu Jun 16 10:33:49 2022 << This used to be the root fs, inside the SATA SSD
# tune2fs -l /dev/mapper/VolGroupSAT-satvol | grep created
Filesystem created:       Mon Nov 14 14:13:49 2022 << When I bought the NVME and created a new VG just for the SATA drive
