Which main IoT migration aspect should be reviewed for a manufacturing plant?

Sensors are the foundational component of any industrial IoT deployment - they collect real-time data from machinery, production lines, and environmental conditions. In a manufacturing context, the type, protocol compatibility, power requirements, and placement of sensors directly determine the feasibility and design of the entire IoT solution, making them the first and most critical migration aspect to assess.

Security is a critical concern in IoT deployments but is a supporting consideration rather than the primary migration aspect specific to a manufacturing plant's operational technology environment.

Applications consume IoT data but depend on sensors being deployed first - reviewing applications before sensors puts the solution design before the data source.

Wi-Fi infrastructure supports wireless IoT connectivity but is a network transport concern, not the defining characteristic of an IoT migration in a manufacturing context.

Ethernet switches provide wired connectivity for IoT gateways and devices but are infrastructure support elements, not the core IoT migration consideration for a manufacturing plant.
