To follow up on Cheryl's comment that archive and install gives a cleaner and probably more trouble-free way of moving to Leopard, and Larry's comments about issues with upgrading, note that the MacFixIt site reports that numerous users are having startup problems with Leopard when using simple upgrades instead of archive and install or erase and install:
Excerpted from http://www.macfixit.com/ The October 26, 2007 article is "Failure to boot after installing Leopard (Mac OS X 10.)" <begin excerpt> Hundreds of users are reporting an inability to properly startup after installing Mac OS X 10.5 (Leopard). This issue is typified by a successful installation, but a persistent blue screen on the subsequent restart, requiring a forced shut down. Unsurprisingly, virtually every user reporting this problem used a straight upgrade ("Upgrade Install") rather than performing an Archive and Install or Erase and Install as we previously recommended. You could argue that (in theory) most users select "Upgrade Install," hence users reporting problems will cite it. However, the facts that literally every report we've received of this problem so far implicates "Upgrade Install," and many users report that going back and performing an Archive and Install or Erase and Install instead solves the issue are telling. <snipped links to discussions in Apple forums about problems and sample problem reports> The obvious solution, which has already proven successful for most users experiencing this problem, is to simply boot again from your Leopard DVD by holding down the "C" key at startup and choose one of the Archive and Install or Erase and Install options. <end excerpt> Just for your information.
