問題文
A company is migrating 4,000 account records from a legacy system into Dynamics 365 Sales. The migration team wants to minimize the risk of column mapping errors. What should they do?
選択肢
- Export the existing Dynamics 365 data to XML, merge the legacy rows into that file, and import the merged file, because the export already carries the correct column names.
- Split the file into 40 files of 100 rows each, because the wizard maps columns correctly only for small files.
- Import the legacy file as is and rely on alternate keys to create any missing columns automatically.
- Download the Excel template for the account table from the app, add the data to it without adding or changing columns, and then import that file.
