C/C++ application migration to Arm architecture assessment. The App Modernization Assessment tool now offers a dedicated assessment for C/C++ applications to facilitate their migration to Arm-based architectures (such as Google Cloud Axion C4A VMs). This new feature helps you do the following:
- Assess readiness: understand the effort and readiness required to transition your C/C++ applications from x86-based architectures to Arm.
- Identify key challenges: pinpoint potential code portability issues, architecture-specific dependencies, and necessary build system modifications.
- Plan for success: gain insights into testing considerations crucial for a smooth and successful migration to Arm, whether on Google Cloud or other cloud providers like AWS Graviton instances.
Supporting documents for assessment. The codmod tool can now analyze
a directory containing additional supporting documents to the codebase.
The codmod tool supports documentation in textual, PDF, and image (PNG, JPG,
JPEG) formats.
Provide the directory by passing the --supporting-documents <directory> flag
to the create command.
Enhanced productivity with command-line completion. The codmod tool now
supports shell command-line completion for Bash, Zsh, Fish, and PowerShell,
significantly boosting your productivity. This feature lets you quickly
type commands, flags, and arguments by pressing the TAB key to see and
select the available options.
With this feature, you can discover options and see valid flag values.
Additionally, suggestions are context-aware, meaning completions are tailored to
the specific command.
For example, codmod config set [TAB] suggests config keys,
and file path completion is exclusively available for file and directory flags.
For additional details, see
Command-line completion.
Automatic version check and updates. The codmod tool now includes an
automatic version check feature to help you stay up-to-date with the latest
improvements and fixes. Every 24 hours, the codmod tool checks for the
availability of a newer version. If an update is available, a notification
message appears in your terminal with the new version number and a download
link.
You can disable the automatic check at any time using the following command:
codmod config set disable_version_check true.To re-enable automatic checks, simply set the value back to
false. You can always view the current state and other configurations by runningcodmod config list.

New quantitative metrics. The report summary section now includes a summary of key quantitative metrics, providing a quick, data-driven overview of the report at a glance.
The Migration Center App Modernization Assessment tool version 0.9.0 is available in Preview.
The Migration Center App Modernization Assessment, powered by Google Gemini (via Vertex AI), is a tool designed to accelerate your application modernization journey. It offers automated, AI-powered analysis to understand your entire codebase in hours, not months, uncovering dependencies and complexities. This enables organizations to swiftly transition their existing codebases to the cloud by identifying potential blockers and providing tailored recommendations based on Google Cloud best practices, ultimately de-risking and planning your transformation with confidence.
Create custom report from template. Use a document as a template to create a custom report. The report will attempt to match the outline and style of the template document.
Added feedback and support links to HTML report. The feedback and support links point to Google Forms that will be used to gather feedback and support requests.
Added file regex flags. Two new optional flags, --force-include and --force-exclude, have been added to provide user flexibility in file selection.
Removed 2.5-flash-lite-exp from Suggested Models. To improve the quality of generated reports, the support for 2.5-flash-lite-exp model was removed.
Smaller Default Report and new Full Report. The default report has been streamlined to 5 sections, reducing generation time and cost. A comprehensive 12-section report can now be generated using the new create full command.
Added a Content Security Policy (CSP) to improve the security of locally viewed HTML reports.
