  • 6. Understanding Your Business Drivers Be clear on your Reducing complexity? business drivers and Improving performance? project goals and stick to them! Looking to include/improve SAP support Are you considering a platform change? Reducing costs? Outsource hosting or change hosting providers Are you considering a platform change? Are you willing to spend more now to save in the long run? Support challenges? Maintaining support staff in an ever changing environment Training costs 24x7 coverage Developing true “expertise”

  • 10. Heterogeneous Migration Migration from the organization’s current platform to the new platform and hardware specified by the hosting provider Defined as the process of changing either the operating system platform, the database vendor, or both Process in a nutshell: Planning Order new hardware Arrange licensing with SAP (or other vendors) Prep new environment Perform test migration Perform data validation tests Current Data Center Hosted Data Center Plan cutover OS – A OS – B Migrate Instances (over several DB – A DB – B weeks) New Equipment
  • 11. Homogeneous Homogeneous migration to new hardware at the new data center Effectively the process of doing a install and a database restore onto new hardware Process in a nutshell: Planning Order new hardware Prep new environment Perform test migration Perform data validation tests Plan cutover Migrate Instances (over several weeks) Current Data Center Hosted Data Center OS – A OS – A DB – A DB – A New Equipment
  • 12. Physical Migration Physical migration of an organization’s own servers to a new data center Simply ship servers to new data center Process in a nutshell: Planning Planning Planning Plan cutover Ship servers to new data center (potentially over several weeks) Current Data Center Hosted Data Center OS – A OS – A DB – A DB – A Old Equipment

  • 14. Heterogeneous Migrations Benefits Get to most current versions of OS and Database Effectively get a database reorganization Can easily incorporate a Unicode conversion simultaneously Simple back-out plan, restart source instance Potential risks Most complex of the options Data transfer during go-live weekend is critical path event Costs Requires a complete duplication of hardware Consulting costs more than a physical migration Downtime Runtime of export/import can be an issue Generally longest productive downtime requirement
  • 15. Homogeneous Migrations Benefits Most straight forward process Similar to QA refresh or DR test Generally requires shortest downtime Simple back-out plan, restart source instance Can get database reorganization if using export/import method Potential Risks Data transfer during go-live weekend is critical path event None of the benefits of export/import if done by backup or file copy Costs Requires a complete duplication of hardware Downtime Shortest of three options Just data shipment and restore of database Can even be reduced to minutes by using previous day’s backup and rolling logs forward via wide area network
  • 16. Physical Migrations Benefits No new hardware investment Potential Risks Considered most risky Hardware damage during shipment Poor options for a back-out plan – depending on the issue None of the benefits of export/import Downtime Very dependent on distance to travel (hours to days) Cost factors Least costly assuming no new hardware needs to be purchased
  • 17. Combination Migrations Work toward benefits of different migration types based on landscape and requirements Balance cost, risk and benefits Limited hardware investment Handle non-production systems differently than production Upgrade only production, roll old PRD hardware through landscape Refresh landscape (ie. refresh QA or DEV with PRD copy)

  • 19. Other Technical Considerations Networking Define the requirements up front Speed Redundancy Locations SAPGui, 3rd party apps, printing, DR SAPGui Managing SAP Logon Pad through the migration Use of host names not IP addresses Manage through DNS changes
  • 20. Other Technical Considerations Printing Generally a migration has little impact to printing Location of print spool servers is important SAP printer definition changes Active Directory Where does your AD live? May require AD at hosting facility Does AD need to be rebuilt (divestiture or acquisition)?
  • 21. Other Technical Considerations 3rd Party Applications Where do 3rd party applications live? How do they impact network design (EDI, OSS, email, etc)? Should they be co-located with SAP servers? Disaster Recovery How does the move change the DR plan? Do not assume DR is automatically part of hosting arrangement Lots of redundancy – yes Full DR – probably not Most likely move will provide enhanced options for DR
  • 22. Other Technical Considerations Security Will your data be co-mingled? Are you subject to ITAR or like restrictions? Network isolation requirements Should I Migrate to the cloud? Investigate what the vendor is offering as “cloud computing” Great alternative for smaller environments Generally will not provide true data and network isolation More cost effective Physical migration not a consideration

  • 24. Ensuring Ongoing Management Meets SAP Best Practices Is the hosting provider certified by SAP? TIP – Look for these logos Does the hosting provider offer managed services? How many SAP consultants does the provider have on staff? Do they have certified consultants? How many SAP customers do they currently host? If doing a Heterogeneous Migration, do they have that unique certification? Speak to references
  • 25. Avoiding Unexpected Server Costs Can you choose which equipment to use? Some vendors dictate hardware vendor makes and models Must you perform a heterogeneous migration to get there? What are the charges for increasing your footprint? Flat rates By “U” count Complete racks or fractional racks What services will be charged to install additional equipment? Do you have to purchase hardware through the hosting provider?
  • 26. Avoiding Unexpected Disk Costs Are you forced to use their SAN? Usage charges for some services can get pricy! Per GB charges can become expensive SAP landscapes tend to grow quickly ECC, BW, CRM, SCM = Terabytes of storage needed Cost of downtime Are you on a shared SAN with other customers? If they need maintenance done will you also be impacted?
  • 27. Avoiding Unexpected Tape Costs Are you forced to use their backup infrastructure? Usage charges for some services can get pricy! Per GB charges can become expensive SAP landscapes tend to grow quickly ECC, BW, CRM, SCM = Terabytes of storage needed Cost of downtime Are you on a shared tape library with other customers If they need maintenance done will you also be impacted?
  • 28. Avoiding Unexpected Contractual Costs Get tips on what to check for in the contract fine print Look for charges that start out at a reasonable price, but increase dramatically or go to per usage charges after a certain threshold. Example: Flat fee for tape usage up to 1TB, then .40 cents per GB thereafter Find out if there is a predefined outage window When is it? How long is it? What frequency is it required?
  • 29. Avoiding Unexpected Contractual Costs What are the details of the SLA? Uptime Performance Responsiveness Network What is the termination clause? What financing options are available? Can they sell you the hardware? Will they build the price into the overall hosting proposal?
  • 30. Avoiding Unexpected Contractual Costs What other services can be included? Operating system support Database support SAP Basis support Security Network (WAN connectivity) Firewall Any 3rd party application support Active Directory

  • 32. Wrap Up Let business drivers determine if hosting and outsourcing are right for you Look beyond just SAP when evaluating the scope When migrating your SAP environment, ask a lot of questions to determine the right migration methodology, which will hopefully fall into a strategic plan Read the fine print to establish a relationship for the long-term
