I'm trying to move my Time Machine backup from an external USB drive to a new Time Capsule. First I followed the instructions from here from 2010: http://www.macworld.com/article/1146085/migratebackups.html Basically, aborting a backup on the TC, then doing a Restore with Disk Utility from my Time Machine volume to the sparsebundle volume. After about 3 days, it finished, but the verification failed with: Restore Failure Could not restore - Invalid argument Which from the log, appears to be because the checksums didn't match. Next I tried the instructions from here: http://www.cnet.com/how-to/how-to-migrate-time-machine-backups-to-a-new-drive/ Although supposedly it's no longer necessary to use a "Copy Exactly" anymore. When I try doing that, the copy immediately fails with "the volume has the wrong case sensitivity". Indeed, it appears that the TC is formatted as "Case-sensitive, Journaled" and my original TM backup is simply "Journaled", which I thought was recommended. I tried erasing the TC (with AirPort Utility) and there was no change in the format. So now I'm not sure how to proceed. Should I do the first method again, and ignore the checksum error? Or try the second method again, by doing a regular drag-and-drop copy, even though the case-sensitivity of the volumes is different?
