Upgrading AWS CLI From v1 to v2 Using the Migration Tool
Developer Tools Blog
This article introduces the AWS CLI v1-to-v2 Migration Tool, a standalone utility that helps developers identify and resolve compatibility issues when upgrading from AWS CLI v1 to v2.
- Migration tool analyzes bash scripts to detect AWS CLI v1 commands with v2 behavior differences
- Suggests automatic fixes or guides manual resolution of potential breaking changes
- Works independently of CLI installation; compatible with any AWS CLI v1 version
- Interactive mode walks through each flagged command with suggested modifications
- Automatically generates updated script with implemented changes where applicable
- Some issues require manual review; tool flags these for developer attention
- Requires Python 3.9+ and pip; available via pip installation
- Tool errs on side of caution, flagging potential issues even when uncertain
The migration tool streamlines AWS CLI v1 to v2 upgrades by automating detection and fixing of compatibility issues, though manual review of breaking changes is still recommended.
