Installing old OS on new kit
Problem I have here, is that we have just got some new iMac's, shipped with 10.6 Snow Leopard. Our existing suites are full of 10.5 Leopard.
I can image the 10.6 machines with an image off of the 10.5 machines, but the machine insisted on booting in verbose mode no matter what I did. I'm not sure what else may or may not work further down the line, so I have gone with installing 10.6 on the machines (as per how they are shipped).
What puzzles me, is how there is no way I can boot a 10.6 machine off of a 10.5 installation disc to actually install an older operating system which is more favourable to the way things are set up here. Is there something in the firmware that prevents this?
In a PC environment (on the assumption the drivers are available) I could install Win95 on a brand new machine shipped with Win7 if I wanted (OK, that's a bit extreme) but you see what I mean. Why is this not possible out of the box on the iMac's?
Another thing that now concerns me, is will the managed preferences I have set up for all my 10.5 clients (Workgroup Manager) work properly on the 10.6 clients? So far I haven't seen any adverse effects of it not working, but I'm wondering if I am going to hit problems running 10.6 clients with a 10.5 xserve?
Advice, comments welcome.
