Using the Import and Export Function to Migrate Data from a Local Database to an RDS for SQL Server DB Instance

Scenarios

• You have created a local Microsoft SQL Server database.
• The local database version cannot be later than the version of the destination RDS for SQL Server DB instance.
• You want to migrate only tables instead of the whole database.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click in the upper left corner of the page and choose Databases > Relational Database Service.
4. On the Instances page, click the instance name.
5. In the navigation pane on the left, choose Connectivity & Security.
6. In the Connection Information area, click Bind next to the EIP field.
7. In the displayed dialog box, select an EIP and click Yes.
8. Install the SSMS client locally and use the EIP to connect to the RDS DB instance.
   

   Click here to download the SSMS client.

9. Use the script generation tool provided by Microsoft SQL Server to generate a database structure script.

   5. Click Next to generate the script.

10. Use the SSMS client to connect to the RDS DB instance and open the generated SQL script.
    

    You need to create an empty database, and then use the script to create structures in the database.

    1. Right-click the database where data is to be imported and choose Tasks > Import Data.
    2. Click Next.
    3. On the Choose a Data Source page, select a data source and click Next.

       • Authentication: Select Use SQL Server Authentication. Then, set User name to rdsuser, and Password to the password of rdsuser.
       • Database: Select the destination database where data is to be imported.
