Relocalizing industry is a controlled process, where the direction of the flux of people is known, and housing and infrastructure sizing can be planned and handled, and people won't follow the industry if they can't get acceptable living conditions.
Mass migrations from climate change are due to unexpected meteorological events either directly (floods, heat waves, etc), or indirectly (food scarcity, drinkable water shortages, political instability, etc). The scale, location and time are unpredictable. The people concerned will need to migrate and have to live in unsanitary housing camps.
