# Purpose of this Article
There have been multiple scenarios while it comes to SAP (ECC) ERP migration to SAP S/4 HANA. It is
important to understand customers current landscape and used functionalities and modules in current SAP
landscape/system to determine the appropriate S/4 HANA migration scenario.
Determination of migration scenario is so important that based on this understanding only scope, team size
and project valuation (bidding value) can be determined. For example, there could be multiple phases (sub
projects) in one simple e.g. ECC6, EhP7 migration to S/4 HANA 1709.
Identi cation of appropriate migration scenario would help you nalizing following things:
1. Magnitude of Work (Scope)
2. Number of Project Phases

3. Team Size Requirement
4. Project Amount (Bid Amount)
Mainly this article is for sales team involved in approaching customers for SAP migration. I hope it helps them.
Note: This article is mainly for SAP consultants/management who are market goers (Sales Team). Please get
your basics strong before committing anything about S/4 HANA Migration.
In this article we would be focussing on Scenario 6 and Scenario 7. Other Scenarios will be covered in future
articles.
Note: This document is prepared considering that rst, the migration will take place from ECC environment and
required additional functionality would be activated in the migrated S/4 HANA 1709 environment. With this
your customer would be in your hand.
# SAP S/4 HANA Migration Scenarios
Note: A new scenario has been evolved in S/4 HANA 1709 for customers who are already in SAP ERP with
HANA1 (Suite on HANA) or S/4 HANA with HANA1 (S/4 HANA Finance 1503, 1605 and S/4 HANA 1511, 1610)
and want migrate to S/4 HANA 1709 (which is on HANA2). Migration has to be done in two phases:
Phase1: SAP ERP o HANA (Suite on HANA) to SAP ERP HANA2 (Suite on HANA2)
Phase2: S/4 HANA with HANA1 (S/4 HANA Finance 1503, 1605 and S/4 HANA 1511, 1610) to S/4 HANA 1709
(1709 is on HANA2)

# S/4 HANA Migration Concepts (Doc. Splitting and Parallel Ledger/Accounting/HANA2)
Following points help you determining migration scenario in respect to scenario 6 and scenario 7:
1. There is no concept of ‘New GL or ‘Classic GL’ in S/4 HANA
2. New GL is not a pre-perquisite for migrating to S/4 HANA, you can migrate to S/4 HANA from classic GL
3. Migration from Classic GL to S/4 HANA 1610 (1503, 1511, 1605 and 1610) was possible, but subsequently
document splitting was not possible and due to this SAP recommendation was to activate rst New GL
(Ledger introduction and document splitting) and then migrate to S/4 HANA
4. Migration from Classic GL (without activating to New GL) to S/4 HANA 1709 is possible, additionally, now
subsequent document splitting and ledger introduction is possible in S/4 HANA 1709. This is the reason, now
there is no need of doing a project for New GL activation in ECC environment.
5. Need to keep in mind that there might be possible three separate projects for converting ECC on classic GL
to S/4 HANA with document splitting and parallel accounting (additional ledgers).
6. Subsequent Ledger (Parallel Accounting) introduction was possible from SAP S/4 HANA Finance SAP 1605
and S/4 HANA 1610.
7. A new scenario has been evolved in S/4 HANA 1709 for customers who are already in SAP ERP with HANA1
(Suite on HANA) or S/4 HANA with HANA1 (S/4 HANA Finance 1503, 1605 and S/4 HANA 1511, 1610) and
want migrate to S/4 HANA 1709 (which is on HANA2). Migration has to be done in two phases:
# Project Phases for Migrating SAP ECC System to S/4 HANA 1709
Considering there is one SAP ECC customer with classic GLs and he wants to move to S/4 HANA 1709. He also
wants have functionality such as document splitting and parallel accounting (additional ledgers).
Phase 1: ECC Migration to S/4 HANA
a. Preparatory Phase
System Requirement (Unicode Conversion)
Maintenance Planner
Pre-Checks
Custom Code Pre-Parathion
b. Technical Migration (SUM)
Database Migration
Software Upgrade
Data Conversion

c. Delta Customization
d. Data (Functional) Migration (Migration Cockpit)
e. Testing
f. Go-Live
Phase2: Ac va on of Parallel Ledger (Non-Leading Ledger Introduc on)
SAP has two approaches to meet mul GAAP repor ng requirements i.e. the account approach and the ledger
approach
1. Preparatory Phase
2. Execu on Phase
3. Post – Processing Phase

Phase3: Activation of Document Splitting
1. Preparatory Phase
2. Execu on Phase
3. Post – Processing Phase
(Further detailing can be obtained from this blog https://blogs.sap.com/2017/12/11/subsequent-document-

Note: No SLO service is required for activating document splitting subsequently. Standard document splitting
activation cockpit is available in IMG node in S/4 HANA 1709.

HANA 1709’.
