# Migrating a Launch Configuration to a Launch Template

AWS has deprecated the launch configuration feature, which has been replaced by launch templates. You can migrate an existing launch configuration to a launch template by following the procedures given here. This procedure will use the AWS web UI (management console).

ArcSight recommends that you migrate any existing launch configurations to launch templates as soon as possible.

1. In AWS, locate and browse to the EC2 Configuration dashboard.

2. From the list of launch configurations, select the configuration you want to migrate.

3. Click Copy to launch template, and from the drop-down, select Copy Selected.

1. On the Copy to launch template dialog, validate the new launch template name and then click Copy.

1. The new template is displayed in the list of launch templates. You are now ready to replace your existing launch configuration (already in use) with the new launch template.

2. Navigate to the Auto Scaling groups console.

1. Select your Auto Scaling group and click Edit.

1. Scroll down to the Launch configuration section and then click Switch to launch template.

1. Select your newly-created launch template. On the Launch template dialog, review and verify your configuration, and when ready, scroll down and click Update.

1. You can now delete the old launch configuration. In the list of launch configurations, select the old configuration.

2. Click Actions, and from the drop-down select Delete launch configuration.
