RISE with SAP S/4HANA Cloud, private edition, will hereafter be referred to as “PCE”.
After finishing this course, you should know and be able to explain:
➢ The supported versions and migration scenarios
➢ The storage guidelines for migrations
➢ The high-level migration process flow
➢ The general system build timeline for migrations
Learning Objectives

3
Migration scenarios are also referred to as ‘brownfield’ scenarios.
Pure content migrations are not included, as they are based on new/’greenfield’ installations.
Partners and SAP will work hand-in-hand during the migration process.
Migration overview

4
Only releases that have at least 9 months of main maintenance left are supported.
Lower releases must be upgraded before a migration to PCE.
Customers must upgrade to the latest version of S/4HANA as per the dates agreed in the contract
and well before end of mainstream maintenance.

SYSTEM COPY (backup/restore): Desired option as this release is under mainstream maintenance
until 2026
S/4HANA 2022 UPGRADE: Upgrade to latest release is optional
• Releases that have at least 9 months of maintenance (mainstream or extended as applicable) left are only supported. For lower release, an upgrade must be executed before the migration to
PCE. Customers must upgrade to the latest version of S/4HANA well before end of mainstream or extended maintenance.
• If a target release below 1909 is chosen, compatibility of subcomponents (such as additional SKUs deployed on top of S/4HANA) need to be manually verified.

A system is migrated using export/import or using SUM DMO with system move. In both cases the
source database is exported using SAP tools and imported into HANA in PCE.
For this approach the following additional storage needs to be contracted with the customer:
1. Storage needed for the export dump on the migration server. This needs to be analyzed and
calculated based on the database size of the source systems. As the migration server will be
reused for every system (DEV, QAS, PRD...), it should be calculated for the biggest source
database.
2. Storage needed on the HANA DB server for backups. Additional storage, twice the size of
HANA, should be calculated and considered. This storage will allow the migration team to
trigger local backups (at least two, therefore twice the HANA size) at different milestones during
the migration/conversion.
Storage guidelines migration/conversion

10
A system that is already on a supported S/4HANA release or running on the HANA database, and
export/import is not possible anymore. In this case, backup/restore is the method to be used.
For this approach, the following additional storage needs to be contracted with the customer:
Storage needed on the HANA DB server for the backup transferred. There should be additional
storage provisioned with size - one time the calculated HANA database size. The transferred
backup will be moved to this storage, so that the software provisioning manager (SWPM) can
perform the restore.

Migration strategy workshops with customer implementation team C I R A
Workshops are in the responsibility of the partner. Dedicated time in project plan for quality
checks. SAP PL should make sure that partners are aware of SAP standard guidelines.
For Brownfield only: ECS participation in partner meeting I R A Overall responsibility with the partner.
For Brownfield only – HO (handover) for migration R A I I
Perform / confirm the post-migration steps before handing over to
SAP Cloud
I R A
Partner performs the post-processing steps as per documentation and shares the output with
SAP PL. Please keep in mind that the partner post steps for PCE migrations are divided into
two parts.
System HO (handover) from partner to Delivery for SAP Cloud

C I R A Checklist for post-processing must be completed as part of the handover to SAP.
Perform the ECS post-processing and ECS migration checks R A C I C I
Responsibility of ECS to make the system as per ECS standard. Partners need to support in
fixing potential issues identified before handover to the customer.
Orchestrating migration support C I R A
Migration is the responsibility of the customer, typically outsourced to partner. Migration
support from SAP is provided only on a limited basis (e.g., to restart the DB if required).
Migration support / interface support (on exceptional basis) C I R A
Currently this is not a defined S/4HANA PCE service with a few exceptions. Additional charges
may apply.
Ensure adherence with all SAP Cloud Security aspects I R A In case of non-compliance always inform the SAP ECS Security officer.
System hand-over to customer R A I I
PL to trigger system handover process to customer. Recommendation to include partner in the
recipient list for system handover.
Customer sign-off (technical & commercial go-live) I C I Customer responsibility, partner to advise customer.
Technical resolution of the escalations during the delivery (system build) R A C I I
In parallel to standard incident escalation procedure, in case technical expertise is required.
Responsibility is with SAP onboarding team. Partners will be informed in case system handover
dates are endangered (if customer approval is given)
