Is there a Step-By-Step Tutorial for extending the main Qubes LUKS /dev/sda2 partition?

[Que Bees]

I recently upgraded my harddrive (750GB) and cloned over my old harddrive (380GB) which had a default Qubes 3.2 installation on it. Now I'd like to add the unused additional space to the main Qubes partition which appears to be /dev/sda2 and is LUKS encrypted.

What is the most efficient way of accomplishing this, is there an existing tutorial written specifically for Qubes?
 
Is there some sort of Qubes recovery mode I can boot to for this operation? Or should I create an Ubuntu LiveCD and following this guide at https://help.ubuntu.com/community/ResizeEncryptedPartitions:

Boot the desktop, live CD. Use gparted (or any tool) to put unallocated space adjacent, and to the left of your Crypt partition. 
Enlarge the Partition storing the crypt with fdisk. 
Reboot ~ You should always reboot after changing your partition table with fdisk. 
Boot the desktop, live CD. Install & configure the tools (lvm2 and cryptsetup). 
Enlarge the Crypt with cryptsetup. 
Enlarge the (LVM) Physical Volume with pvresize. 
Enlarge the (root) (LVM) Logical Volume with lvresize. 
Enlarge the (root) file system with resize2fs. 
Reboot to your encrypted hard drive. 


Thank you!

The above list looks good. You can use recovery mode from Qubes
installation disk.
