Since the days of Mac OS X 10.3 “Panther” Apple has provided a wonderful utility, Migration Assistant, to help move data between your old and new Macs. With this utility you can easily migrate your installed applications, system settings and user data from your old system to your new one.
On the whole Migration Assistant works very well, performs successfully more often than not, and has gotten better with every subsequent release of Mac OS X. However despite Apple’s best efforts there are times when Migration Assistant can’t or won’t work.
A Manual Mac System Migration is just a fancy term for copying things over. The key is knowing what needs to be moved and how to connect the two machines.
