Mainframe Migration Services

Our Overview

Whether your organization replaces the entire enterprise application system, replaces one application / component at a time, applies localized fixes in one application or modernizes underlying infrastructure environments, our migration services is comprehensive and flexible to meet your organization business and technology needs and requirements.

However, due to well known disadvantages in maintaining mainframe assets, a current trend is emerging to migrated functionality away from mainframe systems over to more relevant and cost-effective options. Singularity Partners offers the expertise for both mainframe migration strategy and implementation.

Our Approaches

Singularity Partners has a multi-pronged approach when looking at options to modernize legacy applications

Total Transformation
Gradual Replacement
Duct Tape Approach (short-term solution)
Improve Existing
No System Change

1. Total Transformation

The entire system is rebuilt using new technology, and the old system is sunsetted. It is built from scratch using standard platforms (e.g., J2EE) or built using a third-party package as a foundation layer.

2. Gradual Replacement

A component/function block of an IT System is replaced with a new technology and moved to production as a separate application while the rest of the system remains on old technology. With time, remaining components/functional blocks are replaced with separate apps and gradually the entire system is rebuilt.

3. Duct Tape Approach

Localized, small-scale changes are performed using new technology to address specific issues in the application while the application core architecture and technology remain the same. A popular approach is to build a new application that will be bolted to the main application to bridge the gap in functionality.

4. Improve Existing

The existing system is modernized to offer better results and efficiency gains through improved design.

5. No System Change

Clients are taking a wait-and-watch approach and not going for any modernization drive or systems change.

Our Approach Comparison

Each of the five types of transformation approaches has its own merits and applicability. Which approach works best for any company depends on its organizational requirements, risk appetite, state of its existing IT infrastructure and competitive landscape.
