Another vote for Synology here. I previously had a DS418play for almost 8 years. Just picked up a DS423+ recently to upgrade and the process was literally as simple as removing the drives from the old NAS, chucking them in the new NAS, and booting up. All my Docker containers, all my credentials, all my licenses were all just there and working, despite being in a new shell.
Great game made by some devs who used to work at Halfbrick (Fruit Ninja/Jetpack Joyride fame). Highly recommend playing with an actual DJ turntable for the full fantasy. Also had a recently released VR mode.
