First, you should have a backup plan for your NAS.  RAID alone isn't enough to keep your data safe - and your volume isn't redundant when you are expanding your storage.

On the mechanics:  To increase the space you need to have at least two of the larger disks.  You don't need to upgrade all three to the same size. 

If you want to end up with four disks in the array, you can hot-insert (NAS running) the first 6 TB drive in slot 4.  After that resyncs, you can hot-swap disk 3.  That will resync twice (the second expansion will use the "extra" space on the 6 TB disk).  FWIW, 2x6TB + 2x3TB would give you the same space as 3x6TB.

If you actually want 3x6TB, then you can't use the empty slot.  Instead hot-swap the disks one at a time, and make sure the resync is completed before moving on to the next.

You can just migrate the disks.  Though I do recommend putting in a scratch disk in the new unit first, and then upgrade the software to the current version.  Then power down, and move the disks over (ideally keeping them in slot order).
