I semi-robotically set up .ssh/authorized_keys so that all 3 users “root”, “waltdnes”, and “user2” on the new machine can ssh in to any of the 3 users on my current desktop, and visa-versa. It’s just a matter of installing apps now.
The hardware does show up differently. With a “My Passport” USB backup drive connected “fdisk -l” shows…

For backups, I manually mount “/mnt/drive1” which is assigned to “/dev/sdb1” in “/etc/fstab”. The backup script first sanity-checks if “/mnt/drive1” is mounted on “/dev/sdb1” and that it has at least 100 GB free space, before attempting the rsync backup. I’ll have to change that to “/dev/sda1” on the new machine.
