Currently my TM backups are on an HFS volume. I would like to switch to APFS (for snapshots etc.)
I assume I have to erase the drive and re-format it as APFS.
What's the 'correct' way to save my current backup history? Can I just copy
Backups.backupdb to another HFS drive, then copy it back to the new APFS drive, via Finder? (With TM turned off of course.)
Also, my current
Backups.backupdb contains backups from 2 machines. I only need to preserve the backups for 1 of them. Can I copy just that subfolder?
