Copy disk image of a lion system on new mac or reinstall everything on a clean lion?

[blow45]

|t's an immense help to just copy everything from one image of a mac to another new one, and I have done it routinely.

I am about to do it on my new mac mini from my air, but I was wondering if anyone has noticed any slowing down from this. Or if some mac site has performed tests of speed and efficiency from copying an image of another mac to a new one vs. reinstalling everything clean. Maybe some files are corrupt and will cause problems? Seeing as lion is a dog (imho opinion and a lot of peoples experience and compared to sl) I wouldn't want to just carry over some rubbish from another install, but it's very convenient.

Maybe someone can suggest that I clean up some files or logs before?

Any views guys?

(Oh and by the way I have to mention for some novices here that the way to do it is clone your old mac via superduper or carbon disk cloner. Then connect the cloned external disk to the mac, boot on the new mac, then set from settings to boot next time (or start up and a younger generation might know it) from said external disk, and then lastly clone said disk into the disk of the new mac with any of the said utilities, piece of cake)

peace. blow.

My opinion is to start afresh which each new computer. That way you don't carry any unwanted baggage to the new system.

Are you sure that the Mini's system has everything the Air needs? OS installs aren't necessarily generic so moving one system optimized for a desktop to a laptop seems ill advised.

IMHO you'd be better off installing from the Air's install disks and then migrating.

it's actually the opposite from the mini to the air. I am taking your advice guys and I ll use migration assistant instead.

I would recommend starting fresh and moving things over as you need them. If you have extra crap on your system that isn't important or isn't needed it's best to leave it behind. The best way to find out what you actually need is to start fresh and download/migrate things over if you need them.

I think you could be headed for a world of pain if you try copying across. A clean installation makes much more sense.
