I have to move apartment, turn off, disconnect and transport the Server One to the other place, a situation that will take approximately 18 hours, during which the device will have to be turned off. Would the Bitcoin Node or oder apps be affected during this time, or what would be the effect for the Server One?
Please let me read your suggestions.
You will have no problems, just shut down the device and make the move. When you bring it back up, Bitcoin (and any other services) will pick up where it (they) left off and sync to latest.
