Integration Specialty

Mainframe Modernization

Unlock the data and processes locked inside your IBM AS/400, without rewriting decades of business logic.

01 / The numbers

92%
of legacy ERPs obstruct CIOs and require alteration to share data
34%
of enterprise customers name legacy ERP as the main reason business objectives fail

02 / The challenge

The cost of a legacy AS/400

Challenges

  • Deep AS/400i knowledge required to interact with legacy code
  • Limited data access capabilities
  • IBM proprietary data formats
  • Integration issues with modern platforms

Problems

  • Operational inefficiencies. Outdated manual processes slow the business response
  • Increased costs. Maintenance and modernization expenses strain budgets
  • Poor user experience. Outdated interfaces, lower productivity, higher error rates

03 / The choice

Modernize, or Migrate?

Both work, on different timelines and with different cost profiles. The shape of the codebase decides which to lead with.

Recommended
Approach

Modernize

A middleware layer (MuleSoft) connects AS/400 to new tech without altering the core. Existing COBOL and RPG assets stay in place and become reachable as modern APIs.

Outcomes

  • Cost-effective modernization
  • Improved business agility
  • Enhanced data accessibility for downstream platforms
Approach

Migrate

Migrate all data and processes from AS/400 to a modern ERP or CRM through integration products. Stronger long-term outcome, larger upfront cost.

Outcomes

  • Significant upfront investment
  • Operational disruptions during cut-over
  • Training and change management overhead across teams

04 / The toolkit

FlorenceNext solution suites

Three modules, one mainframe

We mix and match across engagements. Most clients start with InfoConnect; the other two layer in when real-time data or green-screen automation pushes them.

06 / Case study

A luxury fashion brand modernises its ERP

An international luxury fashion brand operating across 100+ locations needed to modernise its legacy ERP infrastructure to streamline operations and support rapid expansion. The existing system obstructed data sharing, slowed business processes, and proved difficult to adapt to evolving technology.

Main goals: cost savings through reduced IT complexity, maintenance and support; agility and scalability for changing business needs and growth; a scalable, adaptable order management system processing orders in near real time.
