 I assume you mean two new bigger drives (or more, if you have spare
 components in the RAID).

 Yes, that is one option. But you can also go via a temporary second
 raid set.
 
 Most easy way: if you have enough SATA ports to connect all drives at
 the same time:
 
  - configure a new raid on the new drives, with the desired partition layout
  - newfs all partitions on it
  - mount both old and new partitions, copy over all the data
  - remove the old raid
 
 If the number of SATA ports is restricted, you can do it with RAID-1 halfes
 instead:
 
  - fail one of the drives in the old set, remove the drive
  - install the new (bigger) drive
  - create a new raid-1 set with one missing component and the new drive
  - continue as above (desired partition layout, newfs, mount, copy)
  - remove the old drive, add the other new drive
  - add the other new drive to the new raid set and reconstruct
 
 Usual warnings apply (create backups, ...)
