Debian is one of the easiest in-place upgrades, if not the easiest,
aside from rolling releases. My home server, currently Debian 12,
started life as Debian 6. There have been drive transplants and drive
cloning, 3.5" HDD to NVMe SSD in the most recent incarnation. And I had
to reinstall the base OS a couple of times, and then restore files from
backups, for reasons unrelated to the upgrade process. Functionally, if
not technically, it's an unbroken line.

Always do your backups, of course, but Debian was designed from the
start to be upgraded in place.
