Re: Debian v.9.2.1 DVDs - how long are they good for?

That's a wee bit overly optimistic.  In practice, you will find it
rather challenging to upgrade from a version of Debian that has been
archived (no longer on the regular mirrors, no longer receiving Long
Term Support).  Right now, the oldest release of Debian that is still
receiving LTS is wheezy (7.x).

A more reasonable projection for the lifespan of Debian installation
media is about 5 years (the length of LTS coverage).

With that said, having full DVDs is pretty much a waste.  Once you
install Debian and get the machine onto the Internet so that you can
upgrade it, you'll find that most of the packages you installed from
the DVDs have been superseded by newer versions, so you'll end up
downloading them all over again anyway.

That's why most of us just use the minimal "netinst" installation images.
Get the basic system installed from physical media, and then download
the packages you want during (or shortly after) the installation,
rather than installing old/buggy versions of the packages from physical
media and then replacing them with newer versions immediately.
