Trailer Lessor completes Informix-to-SQL Server migration in 6 months with Ispirer Systems

A renowned US trailer lessor approached Ispirer Systems with a complex challenge: migrating its entire system from Informix to Microsoft SQL Server. This major project involved migrating three database schemas, three PowerBuilder applications with embedded SQL, an ASP site to ASP.NET, and twelve Web COM components from Visual Basic to C#.

Ispirer Systems successfully completed the migration within six months. The project scope included over 250 thousand tables, 720 thousand lines of PowerBuilder code, 40 thousand lines of Visual Basic, and 80 thousand lines of ASP code. The Ispirer team completed this complex migration in a short time, facing no issues with the intricate database access layers and incorporating optimizations during testing for higher efficiency.
