When you plan to migrate your large workloads to AWS, we recommend that you follow AWS guidance and split your migration process into three stages: assess, mobilize, and migrate. The migration journey involves many factors, including scope (“what?”), strategy (“why?”), and timeline (“when?”), as discussed in Strategy and best practices for AWS large migrations. Each workload you choose to migrate might follow a different migration strategy, as defined in seven common strategies (7 Rs). Most workloads follow the rehost scenario for lift-and-shift migrations. After you select a strategy, you can address the question “how?”, which focuses on at least three aspects (people, technology, and processes).
This guide is for anyone who is planning to migrate their on-premises workloads to the AWS Cloud, including IT and business executives, program and project managers, product owners, and operations and infrastructure managers.
