prefer to keep the continuity of your existing backups on the new drive,
you can—as long as you don't mind jumping through a few hoops.
The procedure is somewhat different depending on whether you're
migrating to a new local disk (discussed next) or to a Time Capsule
(see
Migrate to a Time Capsule or Network Volume
,
ahead).
Migrate to a Local Drive
If you're moving your Time Machine backups from one local drive to
another, make sure both the old drive and the new one are connected
and mounted in the Finder. Then follow these instructions:
1. In the Time Machine pane of System Preferences, turn Time
Machine off.
2. Follow the steps earlier in
Prepare Your Hard Drive
to partition
the
new
disk as a single volume, using either GUID Partition Table
(if you're using an Intel-based Mac) or Apple Partition Map (for a
PowerPC-based Mac).
3. With your new disk still selected, click Restore.
4. From the list on the left, drag your current backup volume (that's
the indented volume name, not the higher-level disk name) into the
Source field.
5. Now go back to the list on the left and drag your
new
Time Machine
backup volume (again, that's the indented volume name, not the
higher-level disk name) into the Destination field. Make sure Erase
Destination is checked.
6. Click Restore. When the confirmation alert appears, click Restore
again.
7. Disk Utility copies your existing backup volume onto the new
volume. Depending on the amount of data you have and the type
of interface your drives use, this process could take anywhere from
hours to days.
