At present, I run 12.2. Would like to go to 13.1. I believe I cannot do that as an upgrade. But can I:
Install 13.1 in ADDITION to 12.2? I go lots of space, 12.2 lives on the 1TB external hard drive, W7 on the internal drive. Of course, I would
remove 12.2 later, after 13.1 is fully set up..
Run 13.1 from the DVD first, to try it out first? I looked once already, but all it says is INSTALL.
Thank you for your advice,

Actually, you can.
With “zypper dup” you should go to 12.3 first, then another jump to
13.1. With the “offline upgrade” method, you can try direct. Of course,
upgrades do fail sometimes, so better make a backup first.

Of course you can. Many people use that alternating install method.

No need to. You can use that partition to install 13.2 or 13.3 when the
time comes.

That’s the full DVD version. There are two other version, the KDE/Gnome
lives, which you can run without installing.

Like Carlos says. I mostly have two partitions fit for use as root partition. Install the newer version on the usused one. Then you still have the old one as a fall-back. And you can of course mount the old one (read-only) somewhere when needed and then check the old configurations in e.g. the old /etc. E.g. when you mount the old 12.1:
mkdir /mnt/os12.2
mount -r /dev/sdnx /mnt/os12.2
cat /mnt/os12.2/etc/sysconfig/network/ifcfg-eth0
to see what the former configuration of eth0 was.
