About the SAP S/4HANA Conversion & System Upgrade (E_S4CON) certification
E_S4CON is SAP’s specialist, technical credential for performing an SAP S/4HANA system conversion and an SAP system upgrade. It sits on the Basis/technical side of an S/4HANA move: where functional consultants handle business processes, this exam is about the tool chain and procedure that actually converts and upgrades the system. For how SAP certification exams work generally, see the certification study guides in our Learning Hub.
The centerpiece is the Software Update Manager (SUM), including the Database Migration Option (DMO) that combines a database migration to SAP HANA with the S/4HANA conversion in one procedure. Around it, the exam covers the conversion phases — planning and pre-checks (Maintenance Planner, the simplification item checks, and SI-check readiness), custom-code adaptation, execution, and follow-on activities — plus modification adjustments with SPDD and SPAU, downtime-optimization techniques, and monitoring and troubleshooting of the procedure. It’s hands-on technical work, not configuration of business processes.
Every PowerKram practice question maps to one of the competency areas below and links to SAP’s own certification content, so a weak spot becomes a specific study step rather than a guess.
E_S4CON competency areas
SAP describes the exam through the phases and tools of a technical conversion and upgrade rather than a fixed percentage per topic. Rather than invent numbers, we list the areas the exam covers and describe each. The SUM/DMO procedure and the conversion phases carry most of the content, so build real hands-on comfort there. Confirm the current scope on SAP’s page before scheduling.
The core tool: running SUM for updates, upgrades, and conversions, and the Database Migration Option (DMO) that migrates to SAP HANA and converts in a single run; SUM phases, configuration, and options.
The S/4HANA conversion path: Maintenance Planner, simplification item (SI) checks and the simplification item catalog, readiness/pre-checks, and the manual preparation and follow-on activities around the technical run.
Adapting custom code for S/4HANA (custom-code checks / ATC) and modification adjustments during the run: SPDD for dictionary objects and SPAU for repository objects.
Techniques to minimize business downtime during the conversion/upgrade, including DMO options and near-Zero-Downtime approaches, and choosing the right strategy for a landscape.
Monitoring the SUM procedure, diagnosing and resolving errors, and handling the surrounding SAP system landscape (systems, stacks, and sequencing) through the conversion and upgrade.

Who E_S4CON is for
E_S4CON suits technical SAP professionals who run or support S/4HANA conversions and upgrades:
- SAP Basis / technology consultants executing SUM and DMO runs.
- System administrators and upgrade specialists planning and running conversions and upgrades.
- Technical migration-team members handling pre-checks, custom-code adaptation, and cutover.
- Technical leads optimizing downtime and troubleshooting the procedure.
The technical conversion sits inside a methodology and a target platform: SAP Activate (E_ACTAI) is the framework that governs the project, SAP S/4HANA Cloud Public Edition (C_S4CPB) is the target platform, and the project side is covered in SAP S/4HANA Cloud Project Manager (C_S4PM), with the wider portfolio positioned in SAP Business Suite (C_BCSBS). For where these skills lead, see the SAP technical consultant and migration career paths in our Career Hub.

Which SAP tool is used to perform the technical execution of an S/4HANA system conversion and upgrade?
- The SAP Fiori launchpad
- The chart of accounts
- The transportation cockpit
- The Software Update Manager (SUM)
Show answer & explanation
Correct: D — the Software Update Manager (SUM). SUM is the technical tool that executes updates, upgrades, and S/4HANA conversions, orchestrating the phases of the procedure.
Why not the others: the Fiori launchpad (A) is a UI, the chart of accounts (B) is finance configuration, and the transportation cockpit (C) is a TM tool — none execute a conversion.
Source: SAP Learning — Software Update Manager → Further reading: PowerKram — SAP Activate (E_ACTAI) →What does the Database Migration Option (DMO) of SUM allow you to do in a single procedure?
- Post a journal entry and close the period
- Migrate the database to SAP HANA and convert to S/4HANA together
- Pick and pack a warehouse order
- Design a Fiori app
Show answer & explanation
Correct: B — migrate to HANA and convert together. DMO combines the database migration to SAP HANA with the software update/conversion in one SUM run, avoiding a separate migration project.
Why not the others: journal postings (A) are finance, warehouse picking (C) is EWM, and Fiori app design (D) is UX — none describe DMO.
Source: SAP Learning — Database Migration Option →Which SAP tool is used to plan the conversion and generate the stack file that SUM consumes?
- The Maintenance Planner
- The dunning wizard
- The Data Transfer Workbench
- The transport organizer
Show answer & explanation
Correct: A — the Maintenance Planner. Maintenance Planner verifies the target, plans the conversion, and produces the stack XML that SUM uses to drive the procedure — a required planning step.
Why not the others: the dunning wizard (B) chases receivables, the Data Transfer Workbench (C) loads Business One data, and the transport organizer (D) manages transports — none plan the conversion.
Source: SAP Learning — Maintenance Planner → Further reading: PowerKram — S/4HANA Cloud Public Edition (C_S4CPB) →What is the purpose of the simplification item (SI) checks before an S/4HANA conversion?
- To schedule freight carriers
- To identify where the target simplifications affect the system so required steps are done before conversion
- To reconcile the bank statement
- To design authorization roles
Show answer & explanation
Correct: B. Simplification item checks flag where S/4HANA’s simplifications affect the current system, listing mandatory preparation and follow-on tasks so the conversion can proceed cleanly.
Why not the others: freight scheduling (A) is TM, bank reconciliation (C) is finance, and authorization design (D) is security — none are SI checks.
Source: SAP Learning — Simplification item checks →During the procedure, which transaction is used to adjust modified ABAP Dictionary objects?
- SPAU
- SPDD
- SE16
- SM37
Show answer & explanation
Correct: B — SPDD. SPDD handles modification adjustment of ABAP Dictionary objects (domains, data elements, tables) during the upgrade/conversion, before data conversion, to preserve custom dictionary changes.
Why not the others: SPAU (A) adjusts repository objects (programs, function modules) — not dictionary; SE16 (C) is data browsing; SM37 (D) is job monitoring.
Source: SAP Learning — SPDD / SPAU adjustments → Further reading: PowerKram — S/4HANA Cloud Project Manager (C_S4PM) →Which transaction adjusts modified repository objects (such as programs and function modules) during the run?
- SPDD
- MM01
- SPAU
- VA01
Show answer & explanation
Correct: C — SPAU. SPAU handles modification adjustment of repository objects (programs, function modules, classes) after the import, letting you keep, reset, or re-apply custom changes.
Why not the others: SPDD (A) is for dictionary objects, MM01 (B) creates material master, and VA01 (D) creates a sales order — none adjust repository modifications.
Source: SAP Learning — SPAU adjustments →Which tool checks custom ABAP code for compatibility with S/4HANA before conversion?
- The ABAP Test Cockpit (ATC) with S/4HANA checks
- The bank reconciliation report
- The warehouse monitor
- The transportation cockpit
Show answer & explanation
Correct: A — the ABAP Test Cockpit (ATC). ATC, using the S/4HANA readiness check variant, scans custom code for objects that must be remediated for S/4HANA (e.g. simplified data models), producing the custom-code adaptation worklist.
Why not the others: bank reconciliation (B) is finance, the warehouse monitor (C) is EWM, and the transportation cockpit (D) is TM — none check custom code.
Source: SAP Learning — Custom code adaptation →A project must minimize business downtime during the conversion. Which approach directly addresses this?
- Running MRP more often
- Adding more general-ledger accounts
- Using SUM downtime-optimization options (such as the downtime-optimized DMO / near-Zero-Downtime techniques)
- Creating more Fiori tiles
Show answer & explanation
Correct: C — SUM downtime-optimization options. SUM offers downtime-minimizing approaches (downtime-optimized DMO and near-Zero-Downtime techniques) that shift work into uptime, reducing the business-downtime window.
Why not the others: more frequent MRP (A), extra GL accounts (B), and more Fiori tiles (D) have nothing to do with conversion downtime.
Source: SAP Learning — Downtime optimization → Further reading: PowerKram — SAP Activate (E_ACTAI) →How does a “system conversion” to S/4HANA differ from a “new implementation”?
- They are identical
- Conversion always deletes all data
- New implementation can only be done on-premise
- Conversion transforms the existing system in place (keeping data and customizations); new implementation is a fresh greenfield build
Show answer & explanation
Correct: D. A system conversion (brownfield) transforms the existing system in place, carrying data and adapted customizations forward; a new implementation (greenfield) builds fresh and migrates selected data. E_S4CON is about the conversion/upgrade path.
Why not the others: they are not identical (A), conversion does not delete all data (B), and new implementations run on-premise or in the cloud (C).
Source: SAP Learning — Conversion vs new implementation → Further reading: PowerKram — S/4HANA Cloud Public Edition (C_S4CPB) →A SUM run stops with an error during a phase. What is the appropriate first technical step?
- Immediately reinstall the operating system
- Delete the database
- Review the SUM logs / phase error, resolve the root cause, and repeat the phase
- Post a manual journal entry
Show answer & explanation
Correct: C — review the logs, fix the root cause, and repeat the phase. SUM is designed so a failed phase can be corrected and repeated; the technician reads the phase log, resolves the underlying issue, and re-runs the phase rather than taking destructive action.
Why not the others: reinstalling the OS (A) and deleting the database (B) are destructive and unnecessary, and a journal entry (D) is unrelated to a SUM error.

Deep dive: E_S4CON scope, the SUM/DMO procedure, and study path
Know the tool chain
The technical conversion runs on a specific tool chain: Maintenance Planner plans it and generates the stack file, SUM executes it, and DMO folds the HANA migration into the same run. Understand what each does and the order they run in — a large share of questions hinges on the correct tool for a step. See SAP Activate (E_ACTAI) →
Prepare, adjust, follow on
Around the run: simplification item checks and readiness/pre-checks tell you what must change first; custom-code adaptation (ATC) plus SPDD (dictionary) and SPAU (repository) preserve your custom objects; and follow-on activities finish the job. Knowing SPDD-vs-SPAU and when each runs is a classic exam distinction. See S/4HANA Cloud Public Edition (C_S4CPB) →
Downtime, monitoring, and landscape
Downtime-optimization options (downtime-optimized DMO, near-Zero-Downtime) reduce the business window; monitoring and troubleshooting keep a run recoverable; and landscape sequencing keeps a multi-system estate consistent. These separate a specialist from someone who has only read the overview. See S/4HANA Cloud Project Manager (C_S4PM) →
Realistic study path
Work through SAP’s conversion and SUM/DMO learning content and, if possible, run a sandbox conversion end to end — Maintenance Planner, pre-checks, a SUM/DMO run, SPDD/SPAU, and follow-on. Practice picking the right tool and step for a stated scenario, since that is how the exam frames its questions. Confirm the live format and cut score on SAP’s page before scheduling.
