I'm replacing my mac mini with a newer model and want to transfer everything from my old mac mini to the new. I have an external hard disk dedicated to my Time Machine backups and an external hard disk dedicated to my iTunes library. Upon first boot I was going to simply point the new mac mini to the time machine backup to effectively "restore" to the new mac mini but I'm concerned how it will handle the external iTunes library? Do I keep the iTunes drive disconnected initially until the restore is complete? When performing the first Time Machine backup on the new mac mini will it recognise the iTunes library as a new library or identify it as the previous library and not re-back it all up?
