Migrate phase

The migrate phase focuses on moving SAP workloads at scale and ensuring that the SAP on AWS infrastructure goes live successfully. To ensure this, the project uses IaC technologies such as AWS CloudFormation to automate SAP provisioning. If you want to use open-source tools, you can read about the SAP repositories built by AWS Professional Services teams that specialize in SAP migrations, as described in the blog post Automating SAP installation with open-source tools.

The project team automates the infrastructure build and provisions the key AWS components in the cloud. You can test the newly provisioned systems and redirect interfaces to new targets while the project team assists in building the AWS infrastructure and resolving SAP-related issues. You can also plan and perform cutover activities while the project team assists in cutting over to the AWS infrastructure and handling SAP tasks, potential risks, and issues. Your data is migrated by using the tools and methods that were defined in the mobilize phase. For production systems, a mock cutover is performed, tested, and fine-tuned. Finally, detailed reporting is provided so you can evaluate critical infrastructure, key performance indicators (KPIs) for the project, and milestones. At a macro level, the migrate phase is completed in a number of waves, as described previously in the overview.

Objectives	Activities
Migrate SAP workloads to AWS Deploy automated IaC systems Put basic operational procedures in place Cut over to SAP on AWS and go live Run the SAP on AWS go-live assessment Go live with operations	Run IaC systems and set up the architecture on AWS Set up migration tools Automate provisioning of the operating system, file systems, and databases Migrate SAP workloads Perform testing, defect resolution, and basic performance-tuning Automate operational procedures such as backups, automatic scaling, and monitoring Cut over and go live
Inputs	Outputs
Outputs from the mobilize phase AWS best practices for migration Migration tools	Report on enabled AWS services Report on running SAP workloads on AWS Report on open and resolved defects Test reports Cutover report

The following diagram provides a simplified example of the migrate phase (in green) as part of the full migration process. It shows the SAP production systems being migrated in two waves.
