Extract text from DMA files
To convert your DMA file to another format, you need Data Migration Assistant or other Database software.
To convert other file formats to the "Migration Assessment Project" file type, you need software like Data Migration Assistant or a similar tool.
The .DMA extension is a notorious source of confusion because it is shared by three distinct, incompatible enterprise environments. Primarily, it acts as a project file for the Microsoft Data Migration Assistant, encapsulating assessment reports when upgrading SQL Server databases. These files are technically GZIP archives containing XML data and logs. The main constraint here is that unless you have the specific Microsoft utility installed, the file appears as an unreadable binary blob.
Secondly, .DMA files often appear in legacy engineering workflows as archives for IBM Rational DOORS, a requirements management tool. In this context, they are standard ZIP files containing module data. Users frequently encounter these files without access to the expensive, specialized software required to view them natively. Less commonly, you might stumble upon this format as a game asset for the Daybreak Forgelight Engine or even a structural analysis project from Dlubal.
To work around these proprietary locks, your best conversion strategy depends on identifying the internal structure. For Microsoft and IBM variants, the file can often be treated as an archive to extract raw text or XML. For documentation and sharing, the goal is usually converting the internal report data into PDF for archiving or Excel (XLSX) for further analysis.
Convert.Guru analyzes your DMA file, detects the exact format, and lets you read the text inside.
Users also converted DMA32, DACPAC, XDL and EKB files.
If you want to convert DMA file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Data Migration Assistant or similar software from the "Database Migration Project" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to DMA, try Data Migration Assistant or another comparable tool in the "Database Migration Project" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DMA converter.
