automated solutions for legacy migration and modernization™

DB-Shuttle® Technology

ATERAS® designed and developed a unique patent-pending automation technology called DB-Shuttle™, which allows mainframe migration with 100% conversion automation, functional equivalency, and equal or better performance at execution.

The ATERAS teams use DB-Shuttle to convert legacy databases to relational technologies and legacy applications to newer, more open languages, using just a few clicks. With DB-Shuttle, ATERAS guarantees retention of customer business rules and retention of the legacy asset on the new platform.

DB-Shuttle provides automated technology that protects legacy assets, reduces maintenance costs, provides agility and flexibility, and enables Service-Oriented Architecture (SOA) within business-critical applications. The new .NET Framework solution integrates the latest versions of Visual Studio and SQL Server.


DB-Shuttle uses the customer source code as data within its massive SQL Server database. It analyzes and manipulates that data during de-construction of the legacy databases and applications, and construction of the replacement relational databases and applications.

The DB-Shuttle technology is unique in the industry because it provides 100% conversion of both databases and application software. Our competitors say a 100% automated solution is impossible. But ATERAS achieves 100% automation in its conversions. Manual intervention is not part of the ATERAS process.


The primary functions of DB-Shuttle include its ability to:

  • Inventory and assess any mainframe applications in great detail, pinpointing those areas that require special attention
  • Convert entire applications to newer languages using customer-specific naming rules, standards and requirements
  • Convert non-relational databases and files to relational technology while preserving all existing data access paths
  • Convert non-relational data to a relational load format without the data ever leaving the customer environment

Patent Pending

The powerful processing engines DB-Shuttle uses to parse, analyze, de-construct, document, re-construct, generate, convert and validate data and applications are patent pending technologies.


Project Center tracks all information about each conversion project, including customer information, language targets, naming standards and conversion overrides.

Navigator performs a rigorous assessment of the collected customer components, including a full inventory and analysis of the component and their inter-dependencies.

SQL Imager de-constructs the non-relational database and file definitions, interprets the data and key relationships, constructs the new DDL to mirror the legacy database structure, and writes all of the COBOL programs required to extract the legacy data to the format required by the relational load utilities.

Transporter engine handles the construction of the new applications with their new languages and database access. Depending upon the type of modernization, the application code language may remain the same (COBOL to COBOL) or may change to a completely new language in the target environment.
