AWS CloudShell migrating from Amazon Linux 2 to Amazon Linux 2023
AWS CloudShell, which was based on Amazon Linux 2 (AL2), has migrated to Amazon Linux 2023 (AL2023). For more information about AL2023, see What is Amazon Linux 2023 (AL2023) in the Amazon Linux 2023 User Guide.
With AL2023, you can continue to access your existing CloudShell environment with all tools provided by CloudShell. For more information about available tools, see Pre-installed software.
AL2023 provides several improvements to development tools, including newer versions of packages such as Node.js 18 and Python 3.9.
Note
In AL2023, Python 2 is no longer shipped with your CloudShell environment.
For more information about the key differences between AL2 and AL2023, see Comparing Amazon Linux 2 and Amazon Linux 2023 in the Amazon Linux 2023 User Guide.

AWS CloudShell Migration FAQs
The following are answers to some common questions about the migration from AL2 to AL2023 with AWS CloudShell.
Will this migration affect any of my other AWS resources, like Amazon EC2 instances running on AL2?
No service or resource other than your AWS CloudShell environment is affected by this migration. This includes resources that you may have created or accessed from within AWS CloudShell. For example, if you have created an Amazon EC2 instance running on AL2 this will not be migrated to AL2023.
What are the packages that have been changed with the migration to AL2023?
AWS CloudShell environments currently include pre-installed software. To learn about the complete list of pre-installed software, see Pre-installed software. AWS CloudShell will continue delivering these packages, with the exception of Python 2. For the complete difference between the packages provided by AL2 and AL2023, see Comparing AL2 and AL2023. For customers with specific package and version requirements that will no longer be met after the migration to AL2023, we recommend reaching out to AWS Support to submit a request.
Can I opt-out from migration
The answer is NO. AWS CloudShell environments are managed by AWS, therefore, all the environments have been upgraded to AL2023.
Can I create a backup of my AWS CloudShell environment?
AWS CloudShell will continue to persist the user home directory. For more information, see Service quotas and restrictions for AWS CloudShell. If you have any files or configurations stored in your home folder and if you want to create a backup for the same, complete Step 6: Create a home directory backup.
