The document discusses best practices for migrating SAP workloads to AWS at scale. It outlines various migration paths including homogenous and heterogeneous options. Key steps in the migration process like data transfer, instance sizing, and cutover planning are covered. A case study of SEEK's SAP migration to AWS is presented, highlighting benefits like cost savings, elasticity, and support for database upgrades. The session emphasizes practices like optimization, testing, and rehearsing the cutover to migrate SAP to AWS with confidence.

Migration Scenario
• Recommended migration path to a supported target
environment?
• Underlying physical host is slow and ageing and running
low on storage?
• Certified tools and required skill sets for the migration?
• Slow network? Transporting large SAP export files to
AWS?
• Strict business downtime window during cutover?

Best Practices and Optimisation
Techniques for SAP Migrations

15. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Pre-Migration Optimisation
• Optimise data transfer to Amazon S3
• Use AWS Snowball or AWS Storage gateway
• Analyse SAP sizing and identify respective instance types
• Assess end user base to determine the region for
deployments
• Identify the APN partner for the migration journey
• Rehearse the cutover a few times and identify any
bottlenecks areas

16. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
• Implement good migration housekeeping
• Use latest generation instance family
• Consider table splitting for large SAP tables
• Parallelise export and import process
• Manually throttle the import parameters (if required)
• Use Snapshots
Migration Optimisation

17. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Post-Migration Optimisation
• Perform integration testing
• Optimise the instance sizes
• Redirect DNS entry for message servers
• Use IT group policies for SCCM for automated SAP logon
entries
• Test System Accessibility from all user locations

How Do You Migrate With Confidence?
Automated, flexible and proven tools to test
migration of SAP applications to run on SAP HANA
(or SAP ASE) in AWS
Value
 Eliminate the unknown: Run migration test to find
actual time, cost and business impact before upgrade
 Less time: Automated migration and rapid cloud
provisioning tools reduce planning and migration time
 Lower cost: Reduce HW cost by 10x with cloud and
reduce consulting cost with automated migration tools

SAP Rapid Migration Test Program With (FAST)
• DMO of SUM* tool has performed system migrations for 25 years, but it requires the
source and target to sit close to each other in the same data center
• DMO with System Move of SUM tool separates the extract process from the import,
allowing the source and the target to be separated. This allows customers to rent test
servers by the hour to control the cost and flexibility
• DMO with System Move of SUM tool does not modify the source system, meaning
customers can run test migrations on their production systems with production data

• Elasticity of non production workloads
• Ability to support HANA migration
• Reduce need for data centre
• Performance gains through right sizing compute
• Visibility of cost

30. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
What’s Next?
• Continue to improve the HA solution
• Continue to work on optimising resource
utilisation through scheduling, reserved
instances, right sizing etc
• Need to explore more AWS services and how
they can support dynamic tiering to reduce
HANA compute
• Move the whole platform to SUSE instead of
Hybrid
• Performance tune code to utilise HANA

Key Takeaways
• Housekeeping
• Use AWS Snowball, AWS Storage Gateway for transferring
large amount of data
• Use FAST (Rapid Migration Program to AWS) for migrating
SAP running on anyDB to SAP ASE or SAP HANA on AWS
• Leverage AWS SAP APN Partners community
• Rehearse. Rehearse. Rehearse. the SAP cutover migration
to AWS
