Destroy unraid array without losing data

[PeteAsking]

Firstly I will note that I have a backup, but as everyone understands restore from backup is a long process and would prefer to avoid this if possible.
 
So I have a normal unraid array of 3 disks (1 parity and 2 data disks).
 
I wish to move all the data using the command line ‘mv’ command to disk 1 in this unraid array.
 
HELP HERE; I then wish to destroy the array and create a new one with only disk 1 present and no parity disk. The data on disk 1 should be retained as I want to move it later.
 
Next I wish to use the freed up disks along with an additional new disk to create a 3 disk btrfs pool with redundancy that I will move everything off the original disk leaving it empty eventually. I believe this has to stay in the array on its own even if unused as unraid cant have a blank array which is totally fine as I wont need to make use of it.
 
How can I achieve this manoeuvre without losing sata that I move to disk one in the HELP HERE section?
 
This will avoid me having to restore from backup. Thanks:)

Use the Dynamix File Manger, easier to move the data without mistakes, then when done do a new config and leave only disk1 assigned.
