AWS Transform for migrations now automates post-launch actions, eliminating the need to configure them server by server. Actions are defined at the account level and applied automatically across all source servers, including multi-account migrations. They run via AWS Systems Manager (SSM) immediately after test or cutover launch, supporting both predefined actions and custom SSM documents. The migration inventory file also gains a new structure for bulk post-launch action configuration per source server. The Transform agent handles end-to-end migration configuration including replication templates, EC2 launch templates, EC2 right-sizing, and post-launch actions.

How does AWS Transform automate post-launch actions during server migrations?
AWS Transform lets you define post-launch actions at the account level, then automatically applies them to every source server across target accounts, including multi-account migrations. Actions execute through AWS Systems Manager (SSM) immediately after test or cutover launch. You can use predefined actions or supply your own SSM document. The migration inventory file now includes a dedicated structure for reviewing and modifying per-server post-launch actions. Teams running large-scale migrations to AWS track capability updates like this on daily.dev to avoid manual configuration bottlenecks.
