I have searched for this topic but have not found anything, so apologies if this is discussed in another thread already - I may not be using the proper terminology in my searches. A link to an existing thread may answer my question... I have been using Time Machine for quite sometime, and backing up to a WD Passport. I need to move to another HD, but was wondering if it is possible to move the backups on the original external HD to the new one, so that I don't have to start all over. I have a strong suspicion that this is not possible, considering the dearth of information on the topic, but any help would be appreciated.
