Well most machines I have now were upgraded from SLES11 (systemd-free) to
SLES12 (systemd). It all depends on the upgrade mechanisms provided:
I had upgraded systems from old-style UNIX filesystem layout (Users in /users,
no /var at all) to modern layout (/home, /var, etc.), and I've migrated systems
from 32bit to 64 bit without reinstalling.
Unfortunately today most software vendors don't really support upgrades; they
all recommend a fresh installation, leaving the task of re-customizing to the

That means: I had to migrate a separate /usr filesystem that we always had
into / myself (SLES12 does not support a separate /usr any more. I guess some
people did not understand what /sbin really meant, or it's just the systemd
bloat). Unfortunately there was no migration task for /var/run to /run, and I
really haven't understood all systemd magic...
