2 separate servers move drives to single new box retain data

[TWiST]

I currently have 2 x N54L with 4 drives in each server, both running separate instances of Xpenology without issue. I have repurposed an i7-2600k system and purchased an H310 card and have a Rosewill server chassis on the way here. Everything is setup on the bench with some throw away extra HDs I had lying around and works great!

 

My questions is, I want to take the HDs out of both of the N54Ls and move them into the new Xpenology server, as seperate arrays obviously and be able to migrate and retain my data? I have done this with single arrays without any problems, but with 2 seperate ones and the Xpenology OS installed on both, I was not sure how I could migrate it all over without incident.

 

Thanks!
