AveriSource Accelerates U.S. Federal Agency Modernization of Mission-Critical Safety and Compliance Systems
The Company
A federal agency within the United States Department of Transportation.
The Challenge
The customer's mainframe costs were increasing as other government agencies moved off the shared infrastructure the agency used. Additionally, leaving the legacy programming environment would give the agency access to a larger pool of maintenance personnel, as well as enable functionality that would better keep pace with evolving business needs.
The Approach
Codebase Maintenance and Backups
In addition to providing transformed applications within the .NET environment, AveriSource provided web service-enabled applications, which replaced and improved upon their legacy systems. AveriSource maintained historical versions, version control, and redundant backups of code and databases via a locally-hosted replicated system. AveriSource also maintained historical versions and performed version control & redundant backups of the migrated (VB.NET) system via a locally replicated system. Backups were performed including historical versions of legacy source code baselines and database schemas for the record-keeping, in addition to facilitating future maintenance.
Database Conversion and Migration
AveriSource converted ADABAS file definitions to relational definitions in SQL Server using AveriSource Refactor™. The data conversion followed an iterative process producing database DDL, database creation scripts, and data migration scripts. Synchronous legacy and target databases were maintained during the testing and deployment of the transformed system.
Historical Documentation Maintenance and Artifacts
AveriSource produced, reviewed, and maintained historical technical logs documenting bug fixes and patches from the inception of the migrated system. Documentation included monthly, iterative AveriSource Platform™ updates, along with full delta (difference) reports against any and all system code drops provided for systems that remained in operation during modernization efforts.
Technical Support and User Training
AveriSource provided steady-state assessment and operational reviews of the migrated systems on a day-to-day basis. AveriSource provided troubleshooting, system anomaly resolution, and bug fixes utilizing an effective three-tiered priority protocol system, including a disaster recovery plan to ensure 100% or near 100% uptime of systems. This AveriSource solution addressed critical concerns of user training by transforming the application from an IBM 3270 green screen to the identical look and feel in the VB.NET environment with no end user re-training required.
The Results
- 50% reduction of maintenance personnel and costs
- 60% ROI in the first year
- 200% improvement in responsiveness
- 97% reduction in time for daily batch jobs from 19 hours to just 35 minutes
