If no major changes are made to the data or schemas,you can skip the verification and migrate data. Then, the evaluation reslut of the destination database is used. If major changes are made to the data and schemas, you must recollect and reevaluate data before you migrate data.

Background information

  • You can verify whether major changes have occurred to the data and schemas of the source database since the last data collection.
  • You must add the CIDR blocks of Advanced Database & Application Migration (ADAM) servers (39.100.131.0/24,47.241.17.0/24) to the source Oracle database. This ensures that ADAM can access the source Oracle database.
    • If the source Oracle database has a public IP address, you can access the database over the Internet.
    • If the source Oracle database has no public IP address, you can access the database by using Alibaba Cloud Database Gateway. Database Gateway is a database connection service that supports remote access to private network databases. Database Gateway allows you to access and manage databases on data centers or other cloud platforms. For more information, see Database Gateway.

        • Instance Region: the region where the database gateway of the source database resides.
        • Database Gateway ID: the ID of the database gateway that is connected to the source database.
        • Source Database Endpoint: the endpoint of the database gateway that is connected to the source database.
    2. Set the parameters of the source database.
      Srouce information
      • Server Name/SID: the server name or system ID (SID) of the source Oracle database.
