8. Planning for your migration

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!
Project Scope

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)

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

13. • 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

14. • Production-sized hardware
 Loan hardware
 Try & Buy programs
• Use the hardware vendor you plan
 Plan to keep the hardware
Hardware Options for Sandbox

15. • 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

16. • 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

17. • 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

18. • 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!

19. • 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

20. • 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
Architect for HA/DR

22. • SGI supports in-place upgrades
• CPU
 Ivy Bridge-EX (today)
 Haswell (expected H2 2015)
 Broadwell (future)
• DRAM
 DDR-3 (today)
 DDR-4 (future)
 Most HANA systems are HA
• Preserve Customer Capex
