Upgrade or new install depends on whether you need any of your old
backup data or not.  Typically when I do an ADSM to TSM upgrade (I am in
the midst of one now for a customer) I do a combination of an upgrade
and a new install.  What I mean by that is that I save the ADSM/TSM
database and recovery log, but uninstall the ADSM code and reinstall the
new TSM code.  I choose to do this because it changes the directory
structure of the installation to the Tivoli paths instead of the old IBM
paths.  I then upgrade the database and am able to restore all of my
customer's old data.

Yet it is possible to run 2 or more TSM servers on 1 machine.  Take a
look at the quick start guide for a brief description on how to do this.
