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.
您可以决定是使用内置的导出/导入机制还是使用第三方解决方案。
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.
然后，执行一系列迁移任务，把配置数据、相关的应用程序数据和数据库模式从当前版本复制并转换到最新版本。
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).
云存储的另一个关键特性是数据的地理分布（地理可扩展性），支持经由一组云存储数据中心（通过迁移）使数据最接近于用户。
