  Executive Summary A CanadianTransportation Giant, based in Calgary, AB, owns approximately 14,000 miles (22,500 km) route miles of rail track all across Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also serves major cities in the United States, such as Minneapolis, Chicago, and New York City. In the last five years the clients IT requirements are dramatically increased and demand for a dynamic IT environment to support the business has grown. Unfortunately the current vendor hosting facilities were still based on the legacy IT infrastructure and operational practices. Any new requirement for SAP systems provisioning was fulfilled by the vendor in 1-2 weeks, which was not acceptable to the client anymore. WFT developed and executed two step approach to address clients current challenges, First to migrate the existing SAP project landscapes to a agile and dynamic WFTCloud, Second to enable a scalable infrastructure for SAP on WFTCloud so that client can provision SAP landscapes on Demand with better reliability and lower cost. The application migration was highly successful, with the result of better application robustness. In addition, monthly hosting charges were reduced by moving the application into the WFTCloud. This whitepaper discusses the migration process for the client , including:  Motivations for Migrating to WFTCloud  Technical aspects of the Migration  Key issues Faced and How WFT addressed them  Migration project TCO

  Overview of theClient Business A Canadian Transportation Giant, based in Calgary, AB, owns approximately 14,000 miles (22,500 km) route miles of rail track all across Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also serves major cities in the United States, such as Minneapolis, Chicago, and New York City. Infrastructure Description To manage its Financials and enterprise resource operations, our client has relied on SAP enterprise resource planning (ERP) software for nearly a decade. The client had become a major customer of SAP, deploying SAP application including SAP ERP, SAP NetWeaver Business Intelligence (BI), CRM, SRM systems, with multiple production instances deployed across the corporation, all of these SAP instances were installed on Microsoft Windows based technologies with SQL Server as the database. The SAP landscape is hosted at a legacy vendor data center and managed by the vendor. Challenges In the last five years the clients IT requirements are dramatically increased and demand for a dynamic IT environment to support the business has grown. Unfortunately the current vendor hosting facilities were still based on the legacy IT infrastructure practices. Any new requirement for SAP systems provisioning

  was fulfilled bythe vendor in 1-2 weeks, which was not acceptable to the client anymore. Motivation for Migrating to WFTCloud As stated earlier the client's SAP landscape is hosted at a legacy vendor data center and the applications were managed by the vendor. Even though the vendor is very renowned there were many limitations existed due to legacy infrastructure as well as the rigid operations management practices. Limited Computing Scalability The Infrastructure the SAP systems were running were on physical servers and was limited in ability to meet client's new project requirements in a timely fashion. The time to procure, install, configure and ready for client exceeded requirements considerably. Lack of Elasticity All new temporary provisioning request from client is treated as new additional servers in the infrastructure, these servers are charged as physical servers and will be charged to the client . There were no provision to "return" the servers to the vendor after temporary or short time requirements are over. Inflexible Storage Area Network (SAN) The Storage Infrastructure was unable to fulfill the organic growth of the systems as well as new project requirements in a timely manner. Also the cost of SAN resources were very high compared to comparable facilities like WFTCloud.

  Long Provisioning Times Coupledwith inflexible legacy hardware infrastructure and rigid operations management procedures, client faced long provisioning times for SAP landscapes. It was more acute in the case of large landscape request to support large SAP projects. Risk of Hardware Failure The Infrastructure SAP systems were hosted are purely physical and legacy High Availability (HA) options used, there were single point of failures and impacted system availability. Cost of Hosting The Cost of hosting per server was very high comparable to similar hosting facilities due to physical server based infrastructure. The pricing also was confusing and variable due to vendors billing practices. Evaluating WFTCloud Hosting To introduce virtualization in the existing hosting facility with additional hardware would cost client more as well as the client lacked expertise to migrate complex SAP systems. Client agreed to evaluate whether SAP migration to WFTCloud would be appropriate . WFTCloud internal architecture, uses virtualization, the client is shielded from the risk of hardware failure, also WFTCloud used SAP HA solutions tailored for Virtual Infrastructure provided continuous SAP application availability.
