This batch script automates the execution of a database migration project using the Microsoft SQL Server Migration Assistant (SSMA) for Access. Here's what the code does step-by-step:

  1. Set Variables
    Variables are defined to store the following paths:

    • SSMA_PATH: Path to the SSMA console executable (SSMAforAccess.Console.exe).
    • PROJECT_FILE: Path to the specific SSMA project file (.ssmaproj) containing migration configuration.
    • LOG_FILE: Path to a log file where the migration process logs will be stored.

  2. Run SSMA Console with the Project File

    • Displays a message: Starting SSMA Access Migration....
    • Executes the SSMA console command using the variables:
      • SSMA_PATH specifies the path to the SSMA tool.
      • /s %Project_File% passes the project file as an argument.
      • /cmd "Connect;Migrate;Synchronize" specifies commands to:
        • Connect to the source and target databases,
        • Migrate the data,
        • Synchronize schema changes.
    • The output and logs from the process are directed to the file specified in LOG_FILE.

  3. Check Exit Status (%ERRORLEVEL%)

    • Checks if the SSMA console command was successful.
    • If ERRORLEVEL (exit status) is 0, it prints: Migration completed successfully.
    • If an error occurs (non-zero ERRORLEVEL), it prints: Migration failed. See log file at: and points to the log file for more details.

  4. Pause the Script

    • At the end, the script pauses to keep the console window open, allowing the user to read the output before closing.

Usage:
This script is used to automatically run a predefined SQL Server migration project for migrating an Access database, log the progress/output, and notify the user of the success or failure of the operation.
