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

Wi-Fi infrastructure is a general network consideration that exists across many deployment types and is not the IoT-specific asset that defines a manufacturing migration.

Manufacturing plants rely on sensors attached to equipment to collect operational data such as temperature, pressure, vibration, and flow rates. Reviewing sensors - including their communication protocols, power requirements, connectivity standards, and compatibility with IoT platforms - is the IoT-specific migration task most critical and unique to manufacturing environments.

Security is a critical cross-cutting concern for any IoT project but is not the primary manufacturing-specific asset to review during migration.

Ethernet switches are network infrastructure components shared with non-IoT deployments and are not specific to the IoT layer in a manufacturing plant.

Applications are the software layer that consumes sensor data and are not the primary IoT migration asset unique to a manufacturing environment.
