You can use the Data Migrator to prepare a specially configured Microsoft Excel spreadsheet that you can use to create new entities or update entity data. Before importing new entities or updated entity data into APM with the Data Migrator, you must have prepared the special spreadsheet that contains the data you want to import.
The easiest way to prepare the import spreadsheet is to paste or type the entity data into a Microsoft Excel spreadsheet template that you download using the Data Migrator. For instructions, see Creating an Import Spreadsheet from a Template.
Alternatively, you can use an existing Microsoft Excel spreadsheet or you can create a new spreadsheet. For instructions, see Creating Your Own Spreadsheet.
