Moving from one Synology NAS to another


I own a DS220J and it is, frankly, rubbish.

I am buying a Synology NAS with more RAM so I am able to view my photo library on the same day as I click on it :wink:

I have 2 drives set up as Raid 1 in my current NAS.

Do I simply take them out and insert them into the new NAS?

What is the best way to move?
