Agent installation fails on servers that run this kernel version. + Kernel versions earlier than 2.6.18-164 are not supported by AWS Transform MGN. Therefore, servers that run these kernel versions cannot be replicated by AWS Transform MGN. **These Linux operating systems are supported:** | Operating system | Supported versions | Prerequisites and Limitations | | --- | --- | --- | | Amazon Linux | 1, 2, 2023 | + Amazon Linux 1 is only supported for AWS to AWS recovery.
+ Amazon Linux 1 is not supported in Canada West (Calgary).

+ The post-launch actions feature is not supported on RHEL 5.x and RHEL 6.x
+ Nitro instance types work with RHEL 7.4\+
+ AWS requires that servers running Red Hat Enterprise Linux (RHEL) must have Cloud Access (BYOL) licenses in order to be recovered to AWS. Note that servers running RHEL Cloud Access Gold Images allow you to access AWS Red Hat Update Infrastructure (RHUI), Red Hat Satellite, or Red Hat Subscription Manager (RHSM). If you are using RHEL Cloud Access Gold Images, you are not able to access RHUI upon failover to AWS unless you link your AWS account to your Red Hat account via the Red Hat portal, and select the Gold image AMI in the launch template.
+ You must select an AWS provided RHEL AMI in the Launch Template for servers running Red Hat Enterprise Linux (RHEL) Pay as You Go (PAYG) images. This allows access to RHUI after migration. Note that usage of these images incurs Amazon EC2 charges for software and infrastructure per AWS Marketplace rates..
