Overview

ROMA Connect supports device import and export. You can export device as a file to the local host or import a local product file to ROMA Connect to migrate device information in batches.

Prerequisites

Before importing a device, ensure that the integration application to which the device belongs has been created. Otherwise, create the integration application in advance.
Before importing a device, ensure that the product to which the device belongs has been created. Otherwise, create the product in advance.
Before importing a device, check whether a duplicate device name exists in the instance to which the device is to be imported. If there are duplicate device names, the device will fail to be imported.
Ensure that the quota of devices meets the requirements before importing the devices.
The files to be imported must be in CSV format and have been encoded using UTF-8 BOM.
When you use an exported file to import devices:
- Create an import file and add the information about the new devices to the file.
  NOTE:
  
  Do not change the name and sequence of table headers in the template. For details about the table header names, see Description of Device Import Files.
- Open the import file and check whether any field value starting with Base64: exists. If there is no field value starting with Base64:, the file is exported from the instance of an earlier version.
  In this case, rename the file by adding -none-base64-prefix to the end of the file name. For example, if the original file name is import.csv, change it to import-none-base64-prefix.csv.
If you use Excel to edit the file to be imported, perform the following operations to save the file:
1. Save the Excel file as a CSV file by selecting Comma Delimited files (*.csv).
2. Use a text editor to open the CSV file saved in 1. Save the file in UTF-8 with BOM.

After the import is successful, you can view the imported devices in the device list.
