    I see no reason this is a dupe - connected, sure, but not a dupe as such. The linked question is 'what is it & why is it so big'. This is 'can I move it', to which the answer is yes. I suppose one may question why it needs to be moved, as in 'is this an XY question?', but it can be, if needed, so I see no reason it can't stand on its own. – Tetsujin Aug 28 '15 at 7:01

You can move the folder to another drive, then use a symbolic link back to the original location, so iTunes can still find it.

A symbolic link is a bit like a shortcut or alias, that the system can use to target a file or folder in another location.
Because of the rather arcane method you'd need to employ in Terminal to generate them, I've always used a little freeware app that sets itself up as a Service in OS X, meaning you can access it through the right-click menu - SymbolicLinker

After Installing this [reboot may be required if it doesn't immediately show in the right-click menu], the procedure would be

  • Move your MobileSync folder to your new drive, Cmd/drag will move rather than copy.
  • Right-click the folder in its new location, go to Services at the bottom of the menu, then Make Symbolic Link
  • Cmd/drag the created link back to the original location in ~Library/Application Support/
  • Change its name to remove the 'symlink' at the end, so it has the original name MobilSync
  • Done.
