Migrate a Time Machine backup

If you've been using Time Machine for backups, there may come a time when you outgrow your backup disk. It's easy enough to plug in a larger disk or buy a Time Capsule (or a larger Time Capsule) and choose that as your new Time Machine destination, but doing that means starting over. If you want to move to a larger disk while maintaining the continuity of your backups, you can. It just means taking quite a few steps.
