8. When the copying is finished, quit Disk Utility, and eject both old
and new backup volumes in the Finder.

Time Machine should pick up where it left off the last time you backed
up to your local drive.
Migrate to a Time Capsule
or Network Volume
If you've been backing up to an external drive for a while and then
you buy a Time Capsule, you may want to move your existing Time
Machine backups to the Time Capsule rather than start over from
scratch. Likewise, if you already have a Time Capsule and buy a larger
one, you may again want to move your backups to the larger volume—
or you may want to migrate from a local drive to a network volume.
Use the same procedure for any of these situations:
1. Follow the steps earlier in this chapter, in Choose a Destination (or
More Than One) , to select the new Time Capsule or network volume
as your backup destination, and let the first backup begin. This
process will go much faster if you have your Mac connected to the
Time Capsule or network via Ethernet—even if you later switch to
Wi-Fi, use a wired connection for this initial backup if possible.
Note: If you're migrating from one Time Capsule to another, see the
2. As soon as Time Machine gets past the “Preparing backup” stage
and starts copying data, move the switch to Off.
3. In the Finder, select your new Time Capsule or network volume and
double-click the folder inside it that contains your Time Machine
backups—the name may vary, but it's usually the only folder on the
disk. (If a Time Capsule doesn't mount automatically, click Connect
As and enter your user name and password.) In this folder is a disk
