A mixing board's real vulnerability is not physical weight, it is the tangle of patched cables and hundreds of tiny fader and knob positions that took time to dial in. Photographing the patch and labeling every line before you unplug anything saves hours at the new setup.
Pro tip: A quick video walkthrough of the board while everything is still connected captures more context than static photos alone, especially for complex routing.
Watch out: Never unplug a mixing board's patch bay without labeling or photographing it first; reconstructing a complex patch from memory afterward can cost far more time than the move itself.
