General launch settings reference - Application Migration Service

General launch settings reference

In the General launch settings section, you can define the following:

  • Instance type right sizing

  • Start instance upon launch

  • Copy private IP

  • Transfer server tags

  • Operating system licensing

  • Boot mode

Instance right sizing – The Instance type right-sizing feature allows AWS Application Migration Service to launch a test or cutover instance type that best matches the hardware configuration of the source server. If you select this option, AWS Application Migration Service will launch a test or cutover AWS instance type that best matches the OS, CPU, and RAM of your source server. Please note that the AWS instance type selected by Application Migration Service when this option is selected will overwrite the instance type defined in your EC2 launch template.

Start instance upon launch – Select this option whether you want to start your test and cutover instances automatically upon launch or whether you want to launch them in a stopped state.

Copy private IP – Select this option if you want AWS Application Migration Service to ensure that the private IP used by the test or cutover instance matches the private IP used by the source server. AWS Application Migration Service monitors the source server on an hourly basis to identify the Private IP and uses the private IP of the primary network interface if this option is selected. Make sure that the IP range of the subnet you set in the EC2 Launch Template includes the Private IP address for this feature to work.

Transfer server tags – Select this option if you want AWS Application Migration Service to transfer any user-configured custom tags from your source servers onto your test or cutover instance. If you select this option, server tags will be transferred. These tags are attached to all source servers, all launched test and cutover instances, and all of the ephemeral resources that are created on your AWS Account during the normal operation of AWS Application Migration Service such as snapshots, Amazon EBS volumes, replication and conversion servers, and security groups.

Operating system licensing – Select this option if you want to Bring Your Own Licenses (BYOL) from the source server into the test or cutover instance. Select “Bring your own license (BYOL)” option if you are migrating a Linux server as all Linux licenses are BYOL by default. Any RHEL, SUSE or Debian licenses will be transferred in their current form to the migrated instance.

For Windows servers, choose the “Bring your own license (BYOL)” option if you want to BYOL your Windows licenses. This will set up a Dedicated Host. All the licenses from the source Windows source server will be automatically transferred to the test or cutover instance. Please note that if you use BYOL licensing for Windows, you have to change the Placement.tenancy type in the EC2 launch template to Host. Otherwise, instance launch will fail.

Boot mode – When a computer boots, the first software that it runs is responsible for initializing the platform and providing an interface for the operating system to perform platform-specific operations. In Amazon EC2, two variants of the boot mode software are supported: Unified Extensible Firmware Interface (UEFI) and Legacy BIOS. The boot mode allows Application Migration Service to launch a test or cutover instance type that best matches the configuration of the source server. You can select between keep the source boot mode or change it to BIOS/UEFI modes.
