My new iMac is arriving tomorrow and I need to transfer everything over to it. I know about Migration Assistant, but I want to know if there will be any complications due to the data I have on an external hard drive. Specifically, I currently have an older (white) iMac hooked up to two 2TB external hard drives. One if for backup but the other one has all my iPhoto and iTunes content on it, including about 1.5 TB of movies and TV shows that I have ripped. None of this material is on the computer's internal hard drive - it is all on the external hard drive. Because my new iMac has a 2 TB internal hard drive, I want to transfer all the iPhoto and iTunes content currently on the external hard drives onto the internal hard drive of the new iMac. Will Migration Assistant handle this and will it be clear what I need to do? Any advice would be appreciated. Thanks.
