Following the release of OS X Mavericks, Apple released not one, but two Migration Assistant updates for OS X customers running versions older than Mountain Lion.
Migration Assistant Update for Mac OS X Snow Leopard v1.1 and Migration Assistant Update for Mac OS X Lion v1.0 are both free downloads from Apple’s servers, and both have one clear goal: “provide compatibility for migrating to a Mac running OS X Mavericks.”
Migration Assistant Update for Mac OS X Snow Leopard v1.1 is for Mac OS X 10.6.8 and later and weighs in at 2.7 MB. Migration Assistant Update for Mac OS X Lion v1.0 is for OS X 10.7.5 and later and weighs in at 5.6 MB.
