How Do I restore my computer's SSD to a new larger SSD? I originally prepped the new Crucial 2 TB SSD in disk utility. I then removed the Mac 1 TB SSD from out of my MacBook Pro and put them both in my Aleratec duplicator. I proceeded to copy. This process seemed to work, however I had 1 TB of free space that was unaccessible. I was unable to move/add that space to the logical volume. I attempted to resize the logical volume but had -5341 error. Partition map to small. After several attempts at this I erased the new 2 TB SSD. 

What type of partition or set up would I need to do to restore the Mac 1 TB SSD to the 2 TB SSD. And what process is recommended for doing so? Use the duplicator or restore in Disk Utility? 

What I thought would be an easy upgrade is turning into nightmare. Does there need to be more then 1 partition on the 2 TB SSD?
You will need to repair the partition map. Disk utility only works within it's known partition maps. You disk duplicator probably didn't do it right. Instead, format the disk again and use disk utility to clone it. You can use the restore functionality for that.
