Migrating data from IBM DB2 to SQL Server

This guide walks you through migrating data from IBM DB2 to SQL Server in a few simple steps using ESF Database Migration Toolkit. Simplify complex migration tasks and save valuable time with our streamlined approach.

Prerequisite:

Step by Step Wizard:

  1. Connect to IBM DB2

    • In the "Choose a Data Source" dialog:
      • Select "IBM DB2"
    • Specify server connection details:
      • Server name: localhost (default)
      • Port: 50000 (default)
    • Enter authentication credentials:
      • Username: db2admin (default)
      • Password
    • In the Database combobox:
      • Enter the source DB2 database name
    • Schema selection procedure:
      1. Click Refresh Schema to load available schemas
      2. Select desired schema from the list

  2. Configure Microsoft SQL Server Destination

    • In the "Choose a Destination" dialog:
      • Select "Microsoft SQL Server"
    • Server connection details:
      • Enter SQL Server host name (optionally with instance name), e.g., localhost\sqlexpress
      • For TCP/IP connections:
        • Specify server port (default: 0 uses named pipes)
        • Provide username (e.g., sa) and password
      • For Windows Authentication:
        • Check the Windows Authentication checkbox
    • Database configuration:
      • Click the Refresh button to list existing databases
      • Select existing database or enter new database name
      • Note: Non-existing databases will be automatically created during migration
    • Schema configuration:
      • Click the refresh button to list existing schemas
      • Select existing schema or enter new schema name
      • Default schema: dbo (if left blank)
      • Note: Non-existing schemas will be automatically created during migration

  3. In "Select Source Table(s) & View(s)" Dialog

    • Select migration objects: Choose tables or views to include in the migration.
      Select Tables & Views

    • Modify table structure: Click the ellipsis (...) button to access table options and schema adjustments.
      Transform

    • Configure field mapping: In the Field Mapping options:
      • Customize destination fields (name, data type, default value, comments)
      • Select data transfer method:
        • Overwrite Table (replace existing data)
        • Empty Data (truncate before insert)
        • Append Data (add to existing data)
        • Skip Table (exclude from transfer)
      • Apply data filters before transfer

  4. Execution Dialog

    • Start migration: Click "Submit" to initiate automated data transfer from IBM DB2 to SQL Server.
      Execute
      Fig. 5: Execute migration
    • Monitor progress: Click "Browse Log" for real-time migration tracking, including issue resolution details.
    • Save configuration: Click "Save as job" to store settings for:
      • Quick reloads of migration jobs
      • Command-line execution (use: dmtc.exe --help for parameter options)

  5. Finished!

    After migration completes, the toolkit generates a comprehensive report for verifying migration accuracy. You can monitor progress as the automated process runs efficiently. For any questions or feedback, contact us – our team is ready to assist.
