Goodbye manual per-server setup! AWS Transform for migrations automates post-launch actions

Hi, it's Shii! Today I found a great update for AWS's migration tooling, and if your team is running large-scale migration projects with AWS Transform for migrations, this one's worth a look!

AWS What's New aws.amazon.com

What was announced?

Over on AWS What's New, AWS announced that AWS Transform for migrations now automates the configuration and execution of post-launch actions through the migration workflow.

Post-launch actions are follow-up steps that run through AWS Systems Manager (SSM) immediately after a test or cutover launch. With this update, you can define actions once at the account level, and they're automatically applied to each source server across your target accounts. Multi-account migrations are supported too.

The story so far

Until now, post-launch actions apparently had to be configured server by server, by hand. The original announcement puts it plainly: it was "the slow, error-prone work of configuring them server by server." The more servers you had to migrate, the more that risk of missed or mistaken configuration piled up.

What changes

Because you only need to define actions once at the account level, migration teams get several concrete benefits:

• No more configuring each server by hand, cutting down a lot of manual effort
• Lower risk of missed or incorrect configuration
• The same actions can be applied in bulk even for large, multi-account migrations
• Teams can move more servers with less hands-on effort

The more servers a migration project involves, the bigger the payoff from this automation is likely to be.

Dive Deep

Let's look a bit closer at how post-launch actions actually work.

• Execution: they run automatically through AWS Systems Manager (SSM), immediately after a test or cutover launch
• Action types: you can use AWS's predefined actions, or bring your own SSM document
• The migration inventory file (used for bulk source server configuration) now includes a new structure for post-launch actions, making it easier to review and modify actions per source server

On top of that, the AWS Transform for migrations agent automates your migration configuration end to end, covering replication templates, EC2 launch templates, EC2 right-sizing, and post-launch actions, while still giving you the flexibility to create and edit any of these individually at the source server level.

This new capability is available in all AWS Regions where AWS Transform is offered.

Wrap-up

• AWS Transform for migrations now automates the configuration and execution of post-launch actions
• Actions defined once at the account level are automatically applied to each source server across target accounts, including multi-account migrations
• Actions run through SSM immediately after test or cutover launch, using predefined actions or your own SSM document
• The migration inventory file has a new structure for post-launch actions, making per-server review and edits easier
• Available in every AWS Region where AWS Transform is offered

For teams migrating large numbers of servers, this is a welcome update that cuts out a lot of manual work!
