Switching to a new ibook

[dnanian]

That's right, though it's difficult to tell if a given build number is actually 'ahead' of a previous one, in a given dot-release. But the *next* dot-release is *usually* good to go (and it's easy to check -- just call Apple or ask on the forums... or even try booting from the clone, as long as you still have the original, no harm done).

You don't *have* to name the backup the same as the original. But, for the reasons above, things work best if you do. You might not notice a problem, but -- for example -- try unmounting the original drive after booting from the clone. If there are files open on it, this is why.
