I have an original Mac Pro 1.1 (2006) running OSX 10.4 and I would like to upgrade to a SSD and upgrade OSX to 10.6. Performing both upgrades as individual processes seems (to me) to be unnecessarily complicated. Is it possible to just 1.) remove the old HD 2.) install the new SSD 3.) format the new SSD from 10.6 disc 4.) install 10.6 from the 10.6 disc 5.) reinstall the old HD and 6.) then copy files from the old HD to the new SSD?
