SAP ECC mainstream maintenance ends. The move is no longer optional, only strategic
The root cause isn't the deadline. It's what's hiding inside the code.
Chapter 02 · The problem

Organizations migrate broken processes and an unquantified black box of custom code.

The old reflex is to inventory all custom code and remediate it. That carries the enterprise's accumulated complexity, much of it redundant, straight into the new platform. The result is higher cost, longer timelines, and a new system that inherits the old system's debt.

Broken processes carried forward. Customizations built around workarounds, not genuine business differentiation.
Scope discovered mid program. Thousands of undocumented custom programs surface after the budget is set and the clock is running.
AI remediation without governance. Generic tools generate suggestions that require weeks of manual validation before any code moves.
Tangled custom code estate → structured plan

Chapter 03 · The MIRA answer

Fix the process first. Carry forward only the custom code that must survive. Keep the core clean for life.

01
Harmonize the process
Harmonize business processes onto SAP standard before a single program is migrated. Reserve customization for genuine differentiation only.
02
Carry forward only surviving custom code
Process harmonization shrinks the custom code estate before a single program is touched. It is the biggest lever on migration cost.
03
Transform with AI acceleration
Assess in 48 hours. Remediate clean core aligned. Every AI recommendation governed by A5E's proprietary knowledge layer and expert review.
04
Keep the core clean for life
Continuous clean core scoring prevents the estate drifting back into the complexity the migration just removed.
The TCO argument

A smaller, cleaner estate costs less to migrate, less to test, and far less to own over time. The client pays once, upfront, to avoid carrying years of unnecessary cost and complexity into the new platform.

Chapter 05 · The proof

Two value pillars. Every conversation, every engagement.

Pillar 01

Risk Mitigation

Advisory surfaces process redundancy before build. Platform surfaces every incompatible program before build
A/B/C/D scoring gives measurable before/after proof the board can see
Every change governed, traceable, and auditable. Expert reviewed, never unsupervised AI on business critical code

'You cannot manage what you cannot see. And you should not migrate what you do not need.'

Pillar 02

TCO Reduction

Process first migration shrinks the code estate before remediation begins. It is the biggest lever on long term cost
AI acceleration compresses remediation far below a manual, all code lift, reducing ABAP developer months significantly
A clean core lowers ongoing cost of ownership. Less to test, upgrade, and maintain for years

'Fix the process, carry forward only what matters, and lower your total cost of ownership for a one time investment.'
