Installing dbt Fusion

Installing dbt Fusion

PROBLEM

dbt Fusion (dbtf) must be installed and working before starting a cross-platform migration. Fusion provides the real-time compilation engine and rich error diagnostics that power the migration workflow.

SOLUTION

Check if Fusion is already installed

dbtf --version

If this returns a version number, Fusion is installed. Verify it can connect to your project:

dbtf debug

Install Fusion

If dbtf is not found, follow the official dbt Fusion installation guide to install it.

Verify installation:

dbtf --version
dbtf debug

Minimum requirements

• dbt Fusion must be able to connect to both the source and target platforms
• Run dbtf debug with each profile to verify connectivity before starting migration

CHALLENGES

Connection errors with dbtf debug

If dbtf debug fails to connect:

1. Verify your profiles.yml has the correct credentials
2. Check that the target warehouse/cluster is running and accessible
3. Ensure any required drivers are installed (e.g., Databricks ODBC/Simba driver)
4. Try the connection with standard dbt debug first to isolate Fusion-specific issues

Fusion version compatibility

If you encounter unexpected parsing or compilation behavior, ensure you're running a recent version of Fusion:

dbtf --version

If Fusion is already installed, you can updated it to the latest version with

dbtf system update
