Heterogeneous MigrationMigration 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 bothProcess in a nutshell:
Current Data CenterOS – ADB – A
Hosted Data CenterOS – BDB – BNew Equipment
PlanningOrder new hardwareArrange licensing with SAP (or other vendors)Prep new environmentPerform test migrationPerform data validation testsPlan cutoverMigrate Instances (over several weeks)

HomogeneousHomogeneous migration to new hardware at the new data center
Effectively the process of doing a install and a database restore onto new hardwareProcess in a nutshell:
Current Data CenterOS – ADB – A
Hosted Data CenterOS – ADB – A New Equipment

Physical MigrationPhysical migration of an organization’s own servers to a new data center
Simply ship servers to new data centerProcess in a nutshell:
Current Data CenterOS – ADB – A
Hosted Data CenterOS – ADB – A Old Equipment

Heterogeneous MigrationsBenefits
Get to most current versions of OS and DatabaseEffectively get a database reorganizationCan easily incorporate a Unicode conversion simultaneouslySimple back-out plan, restart source instance
Potential risksMost complex of the optionsData transfer during go-live weekend is critical path event
CostsRequires a complete duplication of hardwareConsulting costs more than a physical migration
DowntimeRuntime of export/import can be an issueGenerally longest productive downtime requirement
![Page 15: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/15.jpg)
Homogeneous MigrationsBenefits
Most straight forward processSimilar to QA refresh or DR test
Generally requires shortest downtimeSimple back-out plan, restart source instanceCan get database reorganization if using export/import method
Potential RisksData transfer during go-live weekend is critical path eventNone of the benefits of export/import if done by backup or file copy
CostsRequires a complete duplication of hardware
DowntimeShortest of three options
Just data shipment and restore of databaseCan even be reduced to minutes by using previous day’s backup and rolling logs forward via wide area network
![Page 16: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/16.jpg)
Physical MigrationsBenefits
No new hardware investmentPotential Risks
Considered most riskyHardware damage during shipment
Poor options for a back-out plan – depending on the issueNone of the benefits of export/import
DowntimeVery dependent on distance to travel (hours to days)
Cost factors Least costly assuming no new hardware needs to be purchased
![Page 17: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/17.jpg)
Combination MigrationsWork toward benefits of different migration types based on landscape and requirementsBalance cost, risk and benefitsLimited hardware investmentHandle non-production systems differently than productionUpgrade only production, roll old PRD hardware through landscapeRefresh landscape (ie. refresh QA or DEV with PRD copy)

Other Technical ConsiderationsNetworking
Define the requirements up frontSpeedRedundancyLocationsSAPGui, 3rd party apps, printing, DR
SAPGui
Managing SAP Logon Pad through the migrationUse of host names not IP addressesManage through DNS changes

Other Technical ConsiderationsPrinting
Generally a migration has little impact to printingLocation of print spool servers is importantSAP printer definition changes
Active Directory
Where does your AD live?May require AD at hosting facilityDoes AD need to be rebuilt (divestiture or acquisition)?
![Page 21: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/21.jpg)
Other Technical Considerations3rd 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 – yesFull DR – probably not
Most likely move will provide enhanced options for DR
![Page 22: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/22.jpg)
Other Technical ConsiderationsSecurity
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 environmentsGenerally will not provide true data and network isolationMore cost effectivePhysical migration not a consideration

Ensuring Ongoing Management Meets SAP Best Practices
Is the hosting provider certified by SAP? 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
TIP – Look for these logos
![Page 25: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/25.jpg)
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 ratesBy “U” countComplete racks or fractional racksWhat services will be charged to install additional equipment?
Do you have to purchase hardware through the hosting provider?
![Page 26: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/26.jpg)
Avoiding Unexpected Disk CostsAre you forced to use their SAN?
Usage charges for some services can get pricy!Per GB charges can become expensiveSAP landscapes tend to grow quickly
ECC, BW, CRM, SCM = Terabytes of storage needed
Cost of downtimeAre you on a shared SAN with other customers?If they need maintenance done will you also be impacted?
![Page 27: Data Center Migration Strategies for SAP](https://reader034.fdocuments.in/reader034/viewer/2022052315/546b90a4b4af9f752c8b4cc6/html5/thumbnails/27.jpg)
Avoiding Unexpected Tape CostsAre 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 quicklyECC, BW, CRM, SCM = Terabytes of storage neededCost of downtime
Are you on a shared tape library with other customersIf they need maintenance done will you also be impacted?

Avoiding Unexpected Contractual Costs
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

Avoiding Unexpected Contractual CostsWhat are the details of the SLA?
UptimePerformanceResponsivenessNetwork
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?
