Yes, by editing sources.list, running "apt-get upgrade", "apt-get
dist-upgrade", and a few other steps before and in between. The Debian
5 to 6 upgrade is the Ubuntu equivalent of skipping 3-4 Ubuntu
releases!

It's not forbidden (how could it be?!) but a good anti-dote to someone
just "editing sources.list and doing an apt-get dist-upgrade" and
killing his box - if that's what you did.

There are a few people posting on debian-users with upgrade problems
but there'd have to be many more posting if failure is a
general/common scenario.

Furthermore, Debian 6 was released about ten days ago so your failure
in "recent months" might have been due to upgrading to a beta issue
that's been ironed out since.
