Hi, Phatruethai
Error 603413 in Azure Database Migration Service (DMS) typically indicates that the selected source or target database engine is not supported for the migration. To resolve this error, check the following:

Supported Databases: Ensure that both the source and target databases are supported by Azure DMS. Refer to the official documentation for a list of supported database engines.

Correct Migration Path: Verify that you have selected a valid migration path that corresponds to the source and target database types.

Configuration Settings: Review your DMS project configuration settings to ensure that they align with the supported options for your database types.

If the issue persists, consider reaching out to Azure support for further assistance.

@lufor - This has nothing to do with the supported database engine or not. I am currently running into this issue with a v12 to v16 move. I feel that the postgresql v16 environment is riddle with bugs!
