Convert DTPROJ to ASPROJ

Understanding dtproj and asproj file formats

DTProj files are project files used by SQL Server Data Tools (SSDT) for SQL Server Integration Services (SSIS) projects. These files store metadata, configuration, and references for ETL (Extract, Transform, Load) workflows.

ASProj files are project files for SQL Server Analysis Services (SSAS) projects, also managed within SSDT. They contain information about data models, cubes, and analytical structures.

Why convert dtproj to asproj?

Converting a dtproj to asproj is not a typical or direct process, as they serve different purposes: dtproj for data integration and asproj for data analysis. However, you may want to migrate or reuse project structures or metadata between SSIS and SSAS environments.

How to convert dtproj to asproj

There is no direct automated converter for dtproj to asproj, as the project types are fundamentally different. The best approach is to manually recreate the necessary components in a new ASProj within SSDT:

• Open SQL Server Data Tools (SSDT).
• Create a new project: File → New → Project.
• Select Analysis Services Multidimensional and Data Mining Project or Tabular Project as needed.
• Manually add data sources, dimensions, cubes, or tabular models, referencing your original dtproj for data connections and logic.

If you need to reuse ETL logic, consider exporting relevant packages or scripts and integrating them into your SSAS project as data sources or processing scripts.

Recommended software for dtproj to asproj conversion

The best software for this process is Microsoft SQL Server Data Tools (SSDT), available as an extension for Visual Studio. SSDT supports both SSIS and SSAS project types, allowing you to open, compare, and manually migrate project elements.

• Microsoft SQL Server Data Tools (SSDT) for Visual Studio
• Alternative: Visual Studio with the appropriate SSIS and SSAS extensions installed

Summary

While dtproj and asproj files are not directly interchangeable, you can use SSDT to manually migrate project elements. There is no automated tool for this conversion due to the different purposes of SSIS and SSAS projects.
