## 1) Download allMobileDevices.xml from REST API
## 2) Parse XML for serial numbers/device ID
## 3) Parse Master500 CSV and mobileDeviceReport CSV
## 4) When a matching serial is found, create a temp XML with the relevant data
## 5) Use matching device ID to upload the correct XML for the correct device
