Multiple methods are available for uploading your existing Operational Technology device data into the ServiceNow AI Platform.

Service Graph Connector (Excel)
:   You can use the Service Graph Connector (Excel) function to import your Operational Technology data from a populated Microsoft Excel flat-file spreadsheet. You use the spreadsheet in the Integration Hub Extract Transform Load (ETL) to upload this data to the CMDB. To learn more, see [Service Graph Connector for Microsoft Excel](https://servicenow-prod.fluidtopics.net/~PE5PY2v~n9MJXw4vnZoqQ "The Service Graph Connector for Microsoft Excel function enables you to import your existing Operational Technology data from a populated Microsoft Excel flat-file spreadsheet. You use it in the Integration Hub Extract Transform Load (ETL) to upload this data to the Configuration Management Database (CMDB).").

Discovery for Operational Technology
:   To discover Operational Technology devices in designated Purdue levels in your Industrial Control System (ICS) networks, you run the Discovery for Operational Technology function on a recurring basis. It operates in a manner that is similar to the standard Discovery processes. However, its Discovery normally takes place in the Purdue levels 3 through 3.5, depending on which level you select when you create an OT discovery schedule. To learn more, see [Discovery for Operational Technology](https://servicenow-prod.fluidtopics.net/y3L_RNV6wHrdwCOgZgrCTQ "You can run the Discovery for Operational Technology function to discover IT class Operational Technology (OT) devices in designated Purdue levels in your Industrial Control System (ICS) networks. IT class items include switches, routers, and computers that exist both in data centers and in your factories.").
