A European company managing a large-scale insurance processing application, used by millions of customers, had only one remaining on-premises server: an x86 OpenVMS node. Their system was migrated to OCI in parallel with the on-prem node, switching to a royalty-free hypervisor as part of the process.
An industrial company migrated its OpenVMS-based application to x86-64, replacing the unsupported Sybase OpenClient with FreeTDS. The migration required updating embedded SQL and porting 300,000+ lines of code in C, C++, and Fortran. VMware-based virtualization introduced networking challenges but was successfully implemented. Debugger issues slowed testing but were resolved with engineering support. VSI teams assisted with design, migration, and system tuning.
A telecom provider prepared for an x86-64 migration by first modernizing their OpenVMS Integrity environment. Key updates included replacing outdated Java and database interfaces with OpenJDK 8 and FreeTDS. The migration also involved updating COBOL-based applications and replacing legacy ACMS interfaces. These changes reduced risks and ensured a smoother transition to x86-64. The customer received ongoing support from VSI Application Services.
A large company with 430+ remote sites wanted to migrate their Oracle Rdb database to open source PostgreSQL. The application was to remain on an OpenVMS server; however the database was going to be located on a Linux server.
A large telecommunication provider wanted to replace their Alpha servers with Integrities. The core application running on OpenVMS comprised several million lines of complex code written in a variety of languages, including COBOL, Pascal, and C, and interacted with a Sybase database hosted on a UNIX platform, with communication between the OpenVMS-based application and the Sybase database being achieved via the Sybase Open Client API.
