In particular, there is a need for modification of the online services of the first system, including real-time transactions and near real-time transactions. In addition, the batch processing service of the first system needs to be modified. And deploying the modified first system to an original application server (weblogic) for verification, so as to confirm the correctness and validity of the database migration part and the change part of the system application.
Step S104: and according to the conversion relation, the data to be transplanted and the application to be transplanted in the first system are transplanted to the second system.
In an embodiment of the present invention, the data to be migrated and the application to be migrated in the source database are transformed according to the transformation relationship; and configuring the second system according to the converted data to be transplanted and the application to be transplanted.
In an embodiment of the present invention, the converted data to be migrated is unloaded from the source database, and the converted data to be migrated is imported into the target database; and transplanting the converted data to be transplanted to the target database by using a data migration tool of the target database.
