Migration assistant and disk images

I am planning to do a clean install of Snow Leopard. I know I can migrate date from my Time Machine back-up, but can I do so from a disk image of my current laptop configuration?

MacBook Pro, Mac OS X (10.5.6)

Phil,

Yes, you can migrate your data from a mounted disk image. I do have to join V.K in asking why, though. Unless there is some compelling reason to store that data in a disk image, it might be somewhat more secure to have that data stored "in the clear," as it were on a normal volume of a drive. Whether that storage be in the form of a "clone" or just a good copy doesn't really matter. What does is that you don't have the additional layer of complication represented by storage within a disk image.

Again, there's no problem inherent in migrating from the disk image. It's a matter of keeping things as simple as possible, where the safeguarding of your data is concerned. If it is merely a matter of convenience, go ahead and use the disk image method, but keep another copy "in the clear" normally, just in case. A disk image is a single file that, if corrupted, loses all of the data that it contains.

Additional to V.K.'s comments, there's no need for an E&I. Macs aren't like windoze-based PCs. Do note that unless you restore a disk image, you have no way of knowing that it's any good. Go with installing Snow Leopard on top of your current Leopard volume, assuming that you have a bootable backup/clone so you can revert back in case anything goes awry.
