Case Study 1 - Litware, Inc Overview Litware, Inc. is an international manufacturing company that has 3,000 employees. Litware has two main offices. The offices are located in Miami, FL, and Madrid, Spain. Existing Environment Infrastructure Litware currently uses a third-party provider to host a datacenter in Miami and a disaster recovery datacenter in Chicago, IL. The network contains an Active Directory domain named litware.com. Litware has two third-party applications hosted in Azure. Litware already implemented a site-to-site VPN connection between the on-premises network and Azure. SAP Environment Litware currently runs the following SAP products:

• Enhancement Pack6 for SAP ERP Central Component 6.0 (SAP ECC 6.0)
• SAP Extended Warehouse Management (SAP EWM)
• SAP Supply Chain Management (SAP SCM)
• SAP NetWeaver Process Integration (PI)
• SAP Business Warehouse (SAP BW)
• SAP Solution Manager

All servers run on the Windows Server platform. All databases use Microsoft SQL Server. Currently, you have 20 production servers. You have 30 non-production servers including five testing servers, five development servers, five quality assurance (QA) servers, and 15 pre-production servers. Currently, all SAP applications are in the litware.com domain. Problem Statements The current version of SAP ECC has a transaction that, when run in batches overnight, takes eight hours to complete. You confirm that upgrading to SAP Business Suite on HANA will improve performance because of code changes and the SAP HANA database platform. Litware is dissatisfied with the performance of its current hosted infrastructure vendor. Litware experienced several hardware failures and the vendor struggled to adequately support its 24/7 business operations. Requirements Business Goals Litware identifies the following business goals:

• Increase the performance of SAP ECC applications by moving to SAP

HANA. All other SAP databases will remain on SQL Server.

• Move away from the current infrastructure vendor to increase the

stability and availability of the SAP services.

• Use the new Environment, Health and Safety (EH&S) in Recipe

Management function.

• Ensure that any migration activities can be completed within a 48-

hour period during a weekend. Planned Changes Litware identifies the following planned changes:

• Migrate SAP to Azure.
• Upgrade and migrate SAP ECC to SAP Business Suite on HANA Enhancement

Pack 8. Technical Requirements Litware identifies the following technical requirements:

• Implement automated backups.
• Support load testing during the migration.
• Identify opportunities to reduce costs during the migration.
• Continue to use the litware.com domain for all SAP landscapes.
• Ensure that all SAP applications and databases are highly available.
• Establish an automated monitoring solution to avoid unplanned

outages.

• Remove all SAP components from the on-premises network once the

migration is complete.

• Minimize the purchase of additional SAP licenses. SAP HANA licenses

were already purchased.

• Ensure that SAP can provide technical support for all the SAP

landscapes deployed to Azure. You are evaluating which migration method Litware can implement based on the current environment and the business goals. Which migration method will cause the least amount of downtime?
