To transfer your data, you'll need to have both your original drive and your new drive connected at the same time. For single-drive computers (e.g. most laptops), you'll need a device to connect the old drive to your computer after your new hard drive is installed.
If you plan to use your old drive for external storage when the migration process is complete, you can install that drive into an enclosure. We offer many DIY kits with the external enclosure included. Depending on the size and connector type on your drive, you can use one of the following solutions to connect the drive: an External Enclosure, the OWC Drive Dock, or the Newer Technology Universal Drive Adapter. In some instances, though (most notably with MacBook Airs and Retina MacBook Pros), you'll need a special enclosure for Apple's SSD.
For those extremely rare cases where you can't connect your old drive externally, the following steps will be slightly different. See the Special Note at the end of the article for more details.
If the Mac can hold both the new drive and the original drive (for example, a 2006-2012 Mac Pro, or a laptop or Mac mini with a Data Doubler) no enclosure should be necessary. Please contact our customer service team if you are still unsure of which solution is best.
