Questions about migration from 6.2.3 - 918+ (1.04b loader) to 6.2.2 - 3615+ (1.03b loader)

Hi,

 

I've a baremetal hardware with a J3455-ITX mobo and I have DSM 6.2.3 - 918+ (1.04b loader). I have some network problems, unstable and slow network transmissions. In order to discard wired network problems I've tried the same file with an old intel laptop and everything looks fine. I tried another pci ethernet gigabit (chipset Realtek RTL8111G) but I had the same results. Then, I red that the J3455-ITX mobo can have some problems with 1.04b loader and 918+ so I would like to test it with 6.2.2 - 3615+ (1.03b loader).

 

I have some data in my Hard drives that I would like to keep. I have 3 hard disk without raid configuration (in dsm appears as basic raid).

 

Can I install 6.2.2 - 3615+ (1.03b loader) in another USB memory and install it in a spare SDD, and then plug the other three hard drives and migrate them without losing my data?

 

Thanks in advance.

 

PS: I've ordered a J4105-ITX mobo too. Let's see if that one works better.
