MacOS – Copying start volume contents with SuperDuper without copying filesystem

Nothing that I can think of.

My own experience was just - clone, test for a few days, decide all was good.
Then, eventually retire the old drive for good.

You might want to check that the new drive has the correct Recovery Partition in place before making the final swap.

Disk Utility can tell you if the partition is present, if you set the Debug menu to 'show every partition', but I'm not sure how to tell whether it's the Yosemite recovery partition.

Booting into it with no other drive connected would be the certain way; assuming no-one else comes up with a nifty way to ask Terminal etc.

I've run in to this before and the only solution I'm aware of is to reformat your file system. Here's what I suggest you do:

1. Boot off of your OSX install media and use Disk Utility to clone your OS image on to another drive.

2. Reformat your main drive with the file system you want

3. Restore the contents of your backed-up system to the main drive.

You could also go largely through Time Machine for this, but I'd recommend going straight at Disk Utility. TimeMachine refuses to restore from backups that have a different case-sensitivity setting.

Here's a random link to someone's article on cloning a drive with Disk Utility.
