There are only a few examples of where I think that upgrading is better or easier overall:
1) Workstations -- I'd rather upgrade a Win2k Pro (or even WinXP Home) box than reinstall the OS *and* all the software and worry about user settings/data.
2) When a piece of software requires an in-place upgrade instead of allowing a multi-homed approach. Not a large number of these, but enough to where most people should check their software to see if it will support being migrated to another box (the fresh install) while live.
Other than those 2 (there are a few others like the example given by Jorge), there aren't many reasons to not install fresh and sometimes upgrading ends up with other problems appearing that weren't there before.

Although supported when upgrading an OS old stuff from the previous OS is kept and besides that you might run into issues because of incompatibilities with software, drivers, etc. A clean install in combination the migration of the stuff hosted on the old server to the new server gives you a phased approach. Upgrading directly impacts the server and if the upgrade fails you might end up with a trouble server.
IMHO:
* avoid OS upgrades when possible and only use it when really necessary (like for example NT4 PDC -> W2K3 DC, which is mandatory)

Subject: [ActiveDir] Clean install VS Upgrade of Windows 2003
Hey all,
Does anyone have any comments/articles, etc on the benefits or concerns of a clean install of Windows 2003 Server VS an Upgrade? My opinion is that doing a clean install keeps system root clean. It also pristinely adopts the security best practices of 2003 Server. Disk performance will improve as well. Does anyone have anything they can add to this? I have migrated a great portion of my network in a clean install path, and now it is coming into question why did I not choose the upgrade path.
Any comments would be greatly appreciated,
Thanks,
Nate
