I am now using a mid 2009 imac (i5 27") and will be getting the updated mid 2010 imac (15 27"). My question is; can I use a disk image of the 2009 imac and put it on the 2010 model to minimise the switching effort? I know some programmes will have to be reinstalled and I will need to unregister some things like Quark and iTunes. Is it true that you have to make the disk image while the system has started up with the OS X DVD? CCC warns that the image it makes will not be bootable. Can Disk utility restore the new iMac from it? Thanks for the answers. I want to do things right to minimise loss of time!
