Lessons Learned Migrating to S/4HANA and Azure

Lessons Learned Migrating to S/4HANA and Azure

Having delivered more than 100 cloud projects to date, SoftwareONE has gained a lot of experience and insight into how to safely and efficiently operate SAP workloads in the cloud. Over the years, we have seen customers demand not just "lift & shift" migrations of the infrastructure, but deeper landscape modernisations including S/4HANA system conversions as part of their journey to the cloud. Many of our customers chose Azure as their cloud platform for critical SAP workloads. This provided us with the opportunity to further simplify and improve their SAP landscape through the adoption of several "made for SAP" features.

This presentation shares some of the many lessons we have learned through this work. We will cover topics across the technology stack as well as some less technical aspects which leaders should consider while planning their transition to S/4HANA and the cloud.

  16. Lessons Learned

  17. Consider Licensing 01 18

  18. S/4HANA is a new product in SAP’s price book. It

    is not an automatic upgrade from ECC. Licensing Impacts
  19. Licensing Impacts S/4HANA is a new product in SAP’s price

    book, not an automatic upgrade. This affects many other items in SAP’s portfolio, e.g.: 20 Traditional Product S/4HANA version 7011491 SAP Enterprise Master Data Governance 7018852 SAP Enterprise Master Data Governance for SAP S/4HANA 7011620 SAP Access Control 7018703 SAP Access Control for SAP S/4HANA 7017273 SAP Portfolio and Project Management 7018997 SAP Portfolio and Project Management for SAP S/4HANA 7017278 SAP Commercial Project Management 7018669 SAP S/4HANA for Commercial Project Management 7009903 SAP Extended Enterprise Content Management by OpenText 7018891 SAP Extended Enterprise Content Management by OpenText for SAP S/4HANA
  20. S/4HANA Conversion Options 21 Product Conversion Contract Conversion • Retain

    existing contract • Retain user licenses • Convert relevant ‘Engine’ licenses to S/4HANA replacements • Greater ability to mix & match • Replaces existing contract with new • Named User licenses are replaced by new Professional/Functional/Productivity blended user licenses. • Run “original” licenses in parallel until 2027 • More flexibility, but also more uncertainty HANA Licensing Cloud Extension Policy
  21. HANA Enterprise vs. HANA Runtime? Options for Shelfware? Don’t forget

    Linux licenses for HANA Check compatibility of all Add-Ons Licensing Impacts
  22. Licensing Impacts Don’t forget to plan (and budget!) for Licenses!

    We have seen 3-9 months of duration, $10m+ cost impact.
  23. Plan your Region Strategy 02 24

  24. Plan your Region Strategy • Where are your Users? •

    Legal & Privacy • Regulatory Topics • IaaS Feature Availability • Cost of Compute, Network, Storage • Disaster Recovery Case Study: Global Resources Company 25
  25. Leverage Native Cloud Capabilities 03 26

  26. Azure Backup 3rd Party Backup Solution Leverage Cloud-Native: Backups •

    Potential cost savings; simpler architecture • Native platform features: deletion protection, ransomware protection, geo-replication, WORM • Third-party tools usually do not support all of the IaaS features • Trade-off: not all database workloads are supported Case Study: Global Manufacturing Company 27 Geo-Replication Off-Site Tape Storage
  27. Leverage Cloud-Native: Reverse Proxy Case Study: Global Manufacturing Company 28

    3rd-Party Product • Replaced 3rd-party Reverse Proxy with Azure AD Application Proxy • Azure PaaS service; nothing to maintain • Included in most Enterprise-class Microsoft365 licenses (e.g. E3, E5) • Secure: integrated into Azure AD: MFA, WAF features, etc.
  28. Reduce the Cost of Disaster Recovery Case Study: Biotech Company

    in Singapore 29 DB Replication Storage Replication HANA System Replication Azure Site Recovery • Azure Site Recovery for cross-region replication of application servers • Async replication of disks attached to the VM. • RPO of ~10 minutes sufficient for application servers • No compute charges in DR region • HANA System Replication without preload to smaller-sized HANA DR system. • DR system can be much smaller than primary • RPO of <1 minute achievable
  29. Reduce the Cost of Disaster Recovery Case Study: Biotech Company

    in Singapore, Global Manufacturing company 30 HANA System Replication Azure Site Recovery Trigger ASR recovery plan Resize & Start DB *) actual RTO depends on many external factors, e.g. DNS propagation, recovery of Domain Controllers for SSO, etc. • Azure Site Recovery can recover systems semi-automatically from replicated disks • VM-based HANA system is resized and started • RTO of 2-4 hours achievable* • HANA system for DR can be much smaller (cheaper) than primary • We have seen DR of < 1 TB for 5.7 TB primary
  30. Consolidate & Simplify 04 31

  31. Greater Visibility Across Technology Silos 32 • Azure provides a

    true ‘single pane of glass’ across the stack • Replaces disparate specialist tools with single, integrated Azure Portal • Role-Based Access Control enables wide read-only access • “All bugs are shallow given enough eyeballs” – Lower coordination overhead è More agility, higher employee empowerment Network Storage Backup Servers Firewall SAP
  32. Consider Consolidation on HANA • Potential for landscape simplification •

    Reduction in complexity and thus support cost • Performance and robustness improvements • e.g. use HA/DR setup for S/4HANA for other systems as well • Feasibility impacted by HANA licenses Case Study: Biotech Company in Singapore 33 SAP ERP SAP BW SAP GW SAP GTS Oracle HANA MaxDB Oracle SAP S/4HANA SAP BW SAP GW SAP GTS HANA Multi-Tenant System HANA
  33. Start Early with Code Remediation for HANA 34 • Analyse

    code for HANA DB Readiness • Resolve basic HANA compatibility & performance issues early • Leverage automated tooling for simple code fixes • Consider code usage in Production to focus effort, deprecate unused code à Much can be done before moving to HANA Case Study: Energy company in North America
  34. Start Early with Code Remediation for S/4HANA Case Study: Healthcare

    services company in Asia 35 Use automated tooling to scan your ECC system for impact from S/4HANA Simplification Notes • Has functionality been removed by SAP? • Has support ended? • Does the underlying data model change? • Is your code using standard functions that have been changed by SAP? • Is the code even used in production? Impacts can occur to third-party systems that are integrated to SAP.
  35. Master Data Changes 05 36

  36. Business Partner Conversion • Business Partner is a key master

    data object in S/4HANA • The CVI process converts Customer and Vendor objects to BP before S/4HANA migration 37 ECC S/4HANA
  37. Business Partner Conversion 38 ECC S/4HANA Watch out for: -

    Data quality - Configuration inconsistencies - Interfaces with other systems - High data volumes Goal: De-risk the system conversion
  38. Archive Obsolete Customers & Vendors Case Study: Healthcare services company

    in Asia 39 0 200,000 400,000 600,000 800,000 1,000,000 ECC S/4HANA Customer Records 0 20,000 40,000 60,000 80,000 ECC S/4HANA Vendor Records • Significant reduction through analysis and archiving • Executed in parallel to CVI synchronization and data enrichment • Reduces effort for data cleansing and enrichment • Pilot Conversion provided visibility of underlying problems
  39. Summary Consider licensing Use a proven platform Consciously choose regions

    Leverage native cloud capabilities Update practices for the cloud Data cleansing: Look out for Master Data Plan, prepare, pilot – start today! 40
