You can run the preupgrade assistant on your instances running Amazon Linux to check for incompatibilities in packages, libraries, services, command-line options, and configuration files. The assistant produces a report outlining potential incompatibilities and offers suggestions to mitigate them. The preupgrade assistant module for Amazon Linux AMI is available on GitHub under the Apache 2.0 open-source license.
Amazon Linux 2 is the next-generation Amazon Linux operating system that provides a modern application environment with the latest enhancements from the Linux community and offers long-term support. To facilitate migration to Amazon Linux 2, AWS will continue to provide security updates for Amazon Linux AMI 2018.03, the last version of Amazon Linux AMI until June 30, 2020. Amazon Linux 2 is available in all public regions and provided at no additional cost beyond the Amazon EC2 instance usage. To learn more visit the preupgrade assistant documentation page.
