• 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!
Project Scope
9
• 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)
Technical Scope
10
ECC EHP 7 Upgrade
ECC to HANA MIgration
Future Projects
ECC on HANA
• 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

• Build first sandbox immediately Recent production copy
Production sized!
Include integration environment (if possible)
• Include test cycle Unit testing
Integration testing
Performance/Stress testing
Sandboxes & Prototyping
13
• Production-sized hardware Loan hardware
Try & Buy programs
• Use the hardware vendor you plan Plan to keep the hardware
Hardware Options for Sandbox
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
Housekeeping
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!
Data Reduction
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?
Change Management & Test Management
• 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
Solution Manager is your friend!

• Complete Sizing Sandbox system is a great way to size accurately
Sizing tools are good alternative
• Consider technical architecture HANA supports database multi-tenancy
Architecting for S/4HANA
• 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
