The service simplifies your migration by enabling you to make use of the identical automated course of for a variety of purposes.

New Publish-Launch Actions
Because the title of Channy’s submit said, AWS MGN initially supported direct, lift-and-shift migrations. In different phrases, the chosen disk volumes on the supply servers have been instantly copied, bit-for-bit to EBS volumes connected to freshly launched Amazon Elastic Compute Cloud (Amazon EC2) cases.
Immediately we’re including a set of non-obligatory post-launch actions that present further help on your migration and modernization efforts. The actions are initiated and managed by the AWS Techniques Supervisor agent, which might be mechanically put in as the primary post-launch motion. We’re launching with an preliminary set of 4 actions, and plan so as to add extra over time:
Set up Agent – This motion installs the AWS Techniques Supervisor agent, and is a prerequisite to the opposite actions.
Catastrophe Restoration – Installs the AWS Elastic Catastrophe Restoration Service agent on every server and configures replication to a specified goal area.
CentOS Conversion – If the supply server is operating CentOS, the cases might be migrated to Rocky Linux.
SUSE Subscription Conversion – If the supply service is operating SUSE Linux through a subscription supplied by SUSE, the occasion is modified to make use of an AWS-provided SUSE subscription.
Utilizing Publish-Launch Actions
My AWS account has a post-launch settings template that serves as a place to begin, and supplies the default settings every time I add a brand new supply server. I can use the values from the template as-is, or I can customise them as wanted. I open the Software Migration Service Console and click on Settings to view and edit my template:
I click on Publish-launch settings template, and overview the default values. Then I click on Edit to make adjustments:
As I famous earlier, the Techniques Supervisor agent executes the opposite post-launch actions, and is a prerequisite, so I allow it:
Subsequent, I select to run the post-launch actions on each my check and cutover cases, since I need to check towards the ultimate migrated configuration:
I can now configure any or all the post-launch choices, beginning with catastrophe restoration. I examine Configure catastrophe restoration on migrated servers and select a goal area:
Subsequent, I examine Convert CentOS to Rocky Linux distribution. This motion converts a CentOS 8 distribution to a Rocky Linux 8 distribution:
Shifting proper alongside, I examine Change SUSE Linux Subscription to AWS supplied SUSE Linux subscription, after which click on Save template:
To study extra about pricing for the SUSE subscriptions, go to the Amazon EC2 On-Demand Pricing web page.
After I’ve arrange my template, I can view and edit the settings for every of my supply servers. I merely choose the server and select Edit post-launch settings from the Replication menu:
The post-launch actions will likely be run on the acceptable time on the check or the cutover cases, per my choices. Any errors that come up through the execution of an motion are written to the SSM execution log. I can even study the Migration dashboard for every supply server and overview the Publish-launch actions:
Obtainable Now
The post-launch actions can be found now and you can begin utilizing them at this time in all areas the place AWS Software Migration Service (AWS MGN) is supported.
