dist-upgrade won't upgrade

[Marsh <meg@dexa.com>]

I am currently running stable/Woody on my system.  I decided to move
up to something more leading edge "testing".  I changed my
"sources.list" to:

deb http://http.us.debian.org/debian/ testing main contrib non-free

Next I cleaned out the old apt lists "/var/lib/apt/lists".

Then I did an "update":

lists:# apt-get update
Get:1 http://http.us.debian.org testing/main Packages [3237kB]
Get:2 http://http.us.debian.org testing/main Release [81B]
Get:3 http://http.us.debian.org testing/contrib Packages [61.7kB]
Get:4 http://http.us.debian.org testing/contrib Release [84B]
Get:5 http://http.us.debian.org testing/non-free Packages [61.5kB]
Get:6 http://http.us.debian.org testing/non-free Release [85B]

Looks good so far.

Seems very sparse when going from stable to testing.  Did I miss
something in the process?

Thanks
