Collect revision information
Record device, board, modules, OS, firmware, applications and device-management requirements. Confirm the target release with the technical team.
Understand compatibility
One platform may support several OS branches. Validate app, driver, SDK, permission and certification dependencies. Compatibility does not mean every unit can upgrade directly between branches.
Prepare backups and power
Back up data and configuration, and confirm stable power, tools, cables, instructions and recovery. Assign a test unit and a maintenance window.
Validate before rollout
Test application startup, capture, connectivity, permissions, backend and accessories, followed by endurance and exception tests. Deploy in agreed batches after validation.
Obtain matched resources
Firmware, drivers and tools are supplied after hardware verification. Avoid files identified only by similar names, unknown origin or mismatched releases.
