I have my existing servers on Amazon Linux, now we are planning to upgrade it to amazon linux2. How do we do that?
Do we have a set of steps to upgrade or do we need to launch a new Ec2 instance using Amazon Linux2 Image and re-install our apps on top of it?
From Amazon Linux 2 FAQs:
Can I perform an in-place upgrade from an existing version of Amazon Linux AMI to Amazon Linux 2?
No, an in-place upgrade from the existing Amazon Linux image to Amazon Linux 2 is not supported. We recommend that you test your application on a fresh installation of Amazon Linux 2 first before migrating.
