data set migration

基本解释

One may decide to base the migration of the bulk set of data using either a built-in export/import mechanism or, alternatively, a third-party solution.
您可以決定是使用內置的導出/導入機制還是使用第三方解決方案。
A set of migration tasks are performed to copy and transform configuration data, relevant application data, and database schema from the current version to the latest.
然後，執行一系列遷移任務，把配置數據、相關的應用程序數據和數據庫模式從儅前版本複制竝轉換到最新版本。
Another key feature of cloud storage is geographic distribution of data (geographic scalability), allowing the data to be nearest the users over a set of cloud storage data centers (via migration).
雲存儲的另一個關鍵特性是數據的地理分佈（地理可擴展性），支持經由一組雲存儲數據中心（通過遷移）使數據最接近於用戶。
