1、将数据从csp的数据库中迁移至cloud的数据库中。`channel-pub-api-csp`.`cpa_channel_app_source`。条件查询出 95 条记录。如图1
2、`channel-pub-api-cloud`.`cpa_channel_app_source`。总计查询出 158 条记录。如图2
3、将数据从csp的数据库中迁移至cloud的数据库中。字段值变动：id，INSERT `channel-pub-api-cloud`.`cpa_channel_app_source`。编辑命令行脚本。/console/controllers/Migrate20210425Controller.php

}
4、执行命令：./yii migrate20210425/csp-to-cloud。`channel-pub-api-cloud`.`cpa_channel_app_source`。总计查询出 253 条记录，新增 95 条记录。符合预期。如图3
