EC2 Launch Template - Application Migration Service

EC2 Launch Template

Application Migration Service utilizes EC2 launch templates to launch test and cutover EC2 instances for each source server.

The EC2 launch template is created automatically for each Source server that is added to Application Migration Service upon the installation of the AWS Replication Agent.

Note

The EC2 launch template does not need to be edited for most use cases.

Note

You cannot use the same template for multiple servers.

Note

The Launch template can only be edited from EC2.

Note

Many EC2 launch template settings can be changed, but some may not be used by the Application Migration Service launch process and some may interfere with the Application Migration Service launch process. Learn more about individual launch template settings.

Important

You must set the EC2 launch template you want to use with MGN as the default launch template.

Important

The EC2 launch template does not automatically set a specific Subnet. As such, EC2 will attempt to launch in a Subnet within the default VPC. If you have removed your default VPC, EC2 will fail to launch any instance for which there is no valid Subnet specified. Ensure that you specify a Subnet if that is the case, or MGN instance launch will fail.

The Application Migration Service EC2 launch template panel shows a summary of the key template values; to view all the values or to change any of them, choose Modify.

On the About modifying EC2 Launch Templates dialog, choose Modify.

This will redirect you to EC2 > Launch templates > Modify template in a new tab, where you'll be able to make any necessary changes.
