Modernize to the Oracle Cloud


Modernize to Oracle wherever you need it

Turn to TSRI to modernization your mainframe technology for the Oracle Cloud Infrastructure (OCI) quickly and reliably. Our reusable process and scalable solution are the preferred path to the OCI optimized environment and cloud services wherever you need them.

Seamlessly Migrate Valuable Mainframe Technology with TSRI's Certified Engineers and Architects

As an experienced cloud migration provider, TSRI's engineers and architects get mainframe software into the cloud quickly by leveraging our automated refactoring technology. Our near-100% automation process transforms legacy applications to cloud-native applications that natively integrate into the OCI.

Transform your legacy system from any of more than 35 languages, including COBOL, PL/1, JCL, Fortran, MUMPS, PL/SQL and VB6 into modern Java or C# applications in OCI cloud-native target architectures.

TSRI's Migration to the Oracle Cloud Infrastructure

Following a legacy mainframe transformation, TSRI moves the modernized applications to OCI using cloud-specific refactorings such as targeting services, microservices, and containerization. Our migration services take a three-step approach:


Migrate legacy monolithic code to a service-oriented environment

This includes updating language from COBOL to Java or JavaScript, changing databases, and enabling microservices. At this step of the process, the migration would also begin to abstract underlying services from the application.

Integrate service-oriented applications with native cloud services

This could include reorienting code from legacy platforms such as WebSphere DB2 to Microsoft SQL Server and Java. Upgrading to incorporate the latest native architectural interfaces ensures that applications will tightly integrate with the new environment as well as simplify future updates.


Transform native cloud to Docker. Deploy via Kubernetes containers

The movement to containers provides additional architectural abstraction and improved integration of applications within the cloud. Configure your own deployment-specific setup.

Seamless Migrations Every Time

OCI Sample Target Stacks

TSRI has modernized multiple mainframe applications directly to the cloud. Look below to see a modernized example target stack shown where we refactored the application to utilize an MVC-style architecture, introduced a RESTful layer, then modularized and containerized the application itself. TSRI can easily adapt this example to fit your requirements.

OCI Sample Reference Architecture

This sample architecture diagram shows an example of some of the modernizations TSRI has undertaken to migrate to OCI.

  • REST Endpoints expose online programs for legacy CICS interfaces/data
  • DAO injection supports data servers
  • Redis caching addresses roundtripping data access and scalability
  • REST endpoints expose batch-to-Python client jobs, XML, and ETF files
  • VM instances tightly integrate with OCI security and MGT instance injection, .NET core, OCI files, Logic apps, and blob storage

Multi-Tier Distributed Architecture

Migration from a monolithic mainframe architecture and environment to a multi-tier, distributed architecture environment can expose performance issues at the I/O. TSRI's refactoring capabilities remediate within high-performance modern environments but also leverage capabilities such as the REDIS cache addressing roundtripping data access and scalability.

Why Choose OCI?

All cloud providers have strengths that best serve each architecture and application. TSRI works with all of our clients before we begin to tune our JANUS Studio® transformation engine or refactor a single line to determine which cloud instance works best for them. That’s software modernization assured.
