4. • The next version of SAP Business Suite
• New SKU and Code Fork
Only supported with the SAP HANA DB
• S/4HANA themes:
Renewed interface with Fiori UX
Simplified structure with SAP HANA
Cloud deployment first
What is S/4HANA

tenant DB
• HANA Cloud Platform
Extensions
• Quarterly Release
Schedule
• 100% Managed by SAP
• Automatic Updates
Managed Cloud
• Managed HANA DB and
network
• HANA Cloud Platform
Extensions

• 100% Managed by SAP
• Scheduled Updates
On-Premises
• On-Premises or Hosted
• ABAP Customization
• Yearly Release Schedule
• Managed by
Customer/Partner
• Update schedule
defined by customer
9. • Most Customers look for a technical migration first
To S/4HANA or Suite on HANA
• Out of Scope:
HANA Live / Analytics
Simple Finance (i.e. S/4HANA)
• Suite on HANA is the stepping stone to S/4HANA
Then perform code changes, activate S/4HANA extensions
• S/4HANA direct migration expected late 2015
N.B. Migrating to SoH is a great first step to S/4HANA!
1) Define Project Scope
9
10. • Cover all Technical Migration activities
Upgrade to ECC 6.0 EhP7 (if necessary)
Unicode Conversion (if necessary)
HANA Migration
• Restitution
“As fast, faster, or much faster”
ABAP code optimization (some things will be slower)

ECC EHP 7
Upgrade
Unicode
ECC to HANA

11. • Build one Integrated Schedule
Weekly goals
• Include all teams above
And partners!
Assign ownership
• Agree schedule with all teams
Takes time (1-2 weeks)
Aligns with project prep phase
3) Build the Integrated Schedule

12. 4) Define Stakeholders & Comms Plan

13. • Build first sandbox immediately
Recent production copy
Production sized!
Include integration environment (if possible)
• Build it for real!
Full migration with documentation
All functional work
• Include test cycle
Unit testing
Integration testing
Performance/Stress testing
5) Sandbox & Prototype
13
14. • Business Suite systems often venerable
Housekeeping is not always done
A clean system is #1 way to de-risk your project!
• DRAM is expensive!
Basis tables alone cost ~150GB of DRAM below
Multiplied by N production sized systems! TB!
• Run HANA sizing guide
SAP Note 1736976 (BW)
SAP Note 1793345 (ECC)
Look for Big Basis Tables
SAP Note 706478
• Include in Schedule
6) Focus on Housekeeping
14
15. • Disk Databases are inexpensive
Data Reduction rarely considered
• Top 100 tables usually 90% of DB space
Run HANA sizing guide
SAP Note 1736976 (BW)
SAP Note 1793345 (ECC)
• Analyze Top 100 tables
Create action plan
PSA, DSO Change Log deletion (BW)
IDOC, Old Functional Areas, Data Archiving (ECC)
• Remember every GB saved is 10-20GB stored!
7) Data Reduction Program
15
16. • Test Management is critical
Some customers have a mature strategy
Some do not
• Revise your test management strategy
Test Automation
Test Coverage
Test Prioritization
• Reduce your time to complete testing!
How long does it take to complete regression test?
8) Change & Test Management
17. • Make sure you are on the latest latest SP!
http://scn.sap.com/community/abap/custom-code-management
• Custom Code Management Tools (CCMT)
Custom Code Management Cockpit (CDMC)
Usage & Procedure Logging (UPL)
CloneFinder
• Use these tools in combination with:
Testing
Process prioritization by business users
9) Solution Manager is your friend!

18. • Complete Sizing
Sandbox system is a great way to size accurately
Sizing tools are good alternative
• Consider technical architecture
HANA supports database multi-tenancy
10) Architect for S/4HANA
19. • HANA supports system replication
Active/Passive Synchronous (HA)
Multi-tier Asynchronous (DR)
SUSE Linux supports automated host failover
• Very low cost to implement
As compares to e.g. RAC
Most HANA systems are HA
• Even lower cost options
Share QA & DR
11) Architect for HA/DR
20. • HANA Advisory Council
https://blogs.saphana.com/2015/01/12/now-time-plug-sap-hana-customer-communities
• HANA Ambassador Program
North America only
Ask your SAP Account Executive
• Max Attention / Active Embedded
Various services provided
Some useful (going live services, custom code)
• Active Global Support
Going live services
12) Get Support from SAP
21. • Cutover plan touches many teams
But most teams build “MY PLAN”
• Build an integrated plan
All teams, all activities
Number the plan
Align the numbers with the cutover doc
• Track forecast and actual
Tool doesn’t matter (Project, Excel etc.)
13) Build an integrated cutover plan
