Upgrading Capacity of RAID 1+0 by Replacing Drives?

Hi,
Saw a few forum threads talking about doing this with RAID 5, but didn't see any specific indications for a RAID 1+0 and the built-in help has me uncertain how to proceed.

Right now I have four 3TB disks in a RAID 1+0 setup in an OWC ThunderBay IV enclosure.

I would like to replace the existing four 3TB disks with four 6TB disks that SoftRAID just successfully certified.

What is the best way to do this, so that the existing data is "cloned" to the larger capacity drives?

Is it really as simple as adding all four of the new, larger capacity disks to the existing RAID 1+0, waiting for the volume/mirror rebuild to complete, then removing the four old (smaller capacity) disks? Would I then also need to use the volume resize feature to make the volume "expand" to use up all 12 TB available via the new disks?

If that's not the correct process, what's the easiest / fastest way to accomplish the capacity upgrade? Do I need to do this manually? (I.e., create a new RAID 1+0 volume using the new disks, then manually copy the data over from the old one?)

There are two methods:

1. replace each drive one by one, until all four are replaced. Then "resize volume".

Remove two disks from the volume (a "mirror pair"), leaving only two disks, but a mountable volume. Create a 2 drive stripe volume with the 6TB drives. Copy the data over to the stripe volume. Connect the two remaining 6TB drives and "convert" to RAID 1+0. Then you have a RAID 1+0 volume with minimal effort.
