THE SAP ECC LIFECYCLE

Your SI will build S/4HANA. Who’s running ECC while they do?

For the 18–36 months between signing the SI and going live, ECC has to keep running. Allari® runs it — so your team is free for the build — then runs S/4HANA after the SI leaves. Variable cost. No floor. Run-rate compresses each cycle.

WHAT'S COMPRESSING ON THE TEAM

The three forces compressing the ECC team.

During S/4HANA transition, ECC still has to run, the SI needs internal experts, and the business cannot tolerate instability. The pressure concentrates on the same people.

01

ECC still has to run.

Production support, batch, integrations, reporting, month-end, custom processes, and business continuity still matter until cutover is complete.

02

S/4HANA needs the same experts.

The SI needs internal knowledge for design, validation, testing, data, integrations, controls, and decisions.

03

Instability gets inherited.

If ECC operations are messy during the transition, S/4HANA can inherit bad data, bad handoffs, unresolved process debt, and operational noise.

Allari holds the ECC run so S/4HANA can move forward without pulling the same team into every production issue.

Where are you in the journey?

Select a stage to see what we deliver, how long it runs, and why we're structured to do it.

Quantify the complexity before you move.

When: you have not committed to a future-state platform or SI. Risk: choosing a path — S/4HANA, RISE, GROW, third-party support, or leaving SAP — without understanding the operating complexity locked in by ECC custom code, integrations, and team capacity. Allari: independent platform and operating-model assessment — custom code inventory, ATC analysis, integration landscape mapping, data volume audit, and organizational capacity, delivered as a Migration Readiness Scorecard before you sign anything.

What We Deliver

• Custom code inventory & ATC analysis
• Integration landscape mapping
• Data volume & quality audit
• Migration Readiness Scorecard

Why Allari

We don't bundle software or hosting markup into the support fee, and we don't compete for the SI contract. No vendor bias, no implementation conflict — your operations stay objective.

Each option goes directly to the stage page that matches it. If you're not sure, the last card opens our self-serve assessment.

The SI builds S/4HANA. We hold ECC.

The SI is paid to build the new platform. Allari® is paid to run the legacy one. Different incentives, different teams, different accountability — and a support run-rate that should come down each cycle, not compound during the migration.

The contract Allari® signs

• Variable cost. No floor.
• Open book. One number. Nothing buffered.
• Pay for the work. Own the work.

The SI Model

Revenue scales with project scope and duration. Longer engagements are economically rational. Run-state work is a distraction.

The Allari Model

Cost compresses as root causes are eliminated. Faster resolution lowers our own consumption cost. Run-state is the entire engagement.

HOW THE LIFECYCLE READS ACROSS THE TEAM

Three views on the same five stages.

The lifecycle separates run-state work, readiness risk, SI delivery, and post-go-live operations — instead of bundling all four into one implementation budget. Different seats see different parts of the same structure.

The CFO view

Migration cost becomes easier to govern when run-state work, readiness risk, SI drift, and post-go-live operations are separated line items — not hidden inside one implementation budget.

The board view

The five-stage structure protects strategic optionality. The company can evaluate the platform path, prepare the current environment, protect the build team, govern the SI, and stabilize the future platform without pretending one vendor owns every risk.

The migration-lead view

Production work stops pulling the build team backward. Allari holds the run, surfaces operating risk early, and the migration lead gets more room to execute against the SI’s plan.
