You can find instructions for the physical swap lots of places on the Internet, most assume you want to start afresh with your backups. For some of my machines I do, some I do not.
If I want to keep and retain the old backups to be able to restore from them, then I need to copy over the data.
- Go to each
machine that uses the Time Capsule, and turn Time Machine off
- Swap the
hard drive in the Time Capsule and re-assemble
turning the Time Capsule on, use Airport Utility to format the new HD
- Take the
old HD and use a SATA to USB adapter to connect to a Mac laptop
- Make sure
this machine is connected by wired ethernet to the Time Capsule, gigabit
is best: there's a heap of data to copy!
- Mount the
(new) Time Capsule drive in finder
We need to copy the data into the folder called 'Airport Disk'
- On the old
HD look for the volume called 'Data' and in there 'ShareRoot' and in
there you'll find the disk images with all the old backups. Copy what
you need from here into the 'Airport Disk' mentioned above
- It'll take
a while, so be patient
- On the
machine whose backup image you just copied, restart Time Machine, you
may need to reselect the Time Capsule, and the first backup may take
slightly longer than usual.
- For bonus points, remember that all your data is on that old disk totally unencrypted. If you think you might need it, and you have Mac OSX Lion, then use FileVault 2 to encrypt it on the fly ie not loss of data.
