 | reply to ArchAngel21x One advantage to a clean install- it gives you an opportunity to look at all of the different applications you have installed over time and decide which ones are worth carrying over to the new operating system. Also, some applications may need to be abandoned because they have not been (and never will be) updated for the new OS.
A switch to a new OS seems to represent the perfect time for system housecleaning. On my Mac Pro, I intend to write all zeroes to one of the extra hard drives, then install Snow Leopard (Family Pack) on it. While continuing to use Leopard as my main OS, I will add applications to the SL drive as time permits (and as I hear that they are SL-compatible). Finally, when I decide that my SL drive is ready for prime time, I will clone it to my main hard drive using Super Duper. I will also set up my Macbook Pro in Target Disk mode and clone the SL drive over to it.
This is the procedure that I used when I upgraded from Tiger to Leopard. |
