For an enterprise .NET Framework migration, choose the approach according to the outcome you need: Microsoft’s GitHub Copilot upgrade workflow documents assessment, planned code changes and validation across several C# and Visual Basic project types; Amazon Q Developer’s documented IDE transformation focuses on porting Windows-based .NET applications to cross-platform .NET and Linux; and AWS Prescriptive Guidance helps teams choose a broader hosting or architecture strategy. These are different kinds of options, not equivalent products, and none is a universal winner.
What each option is designed to do
The most important distinction is between a code-transformation workflow and a migration strategy. An IDE agent can help assess and change code, but it does not decide whether an application should remain on Windows, move to Linux, be rehosted, or be redesigned. Microsoft documents an upgrade route from .NET Framework of any version to .NET 8 or later, as well as a separate route to .NET Framework 4.8.1 for teams that are not ready to leave full Framework. Microsoft’s Copilot upgrade overview and documented upgrade scenarios describe those paths.
| Option | What its documentation describes | A useful evaluation lens | What remains to verify |
|---|---|---|---|
| GitHub Copilot upgrade | Assessment, dependency and NuGet compatibility analysis, breaking-change identification, task planning, code updates and validation. Documented paths include .NET Framework of any version to .NET 8 or later. C# and Visual Basic scenarios include web, desktop, library, console and test project types, with support varying by scenario. Microsoft’s overview, scenario documentation and project upgrade guide. | Whether a guided assessment-and-change workflow fits the application mix, including libraries and different project types. | Exact support for each project and environment, plus current licensing and operating requirements. The documentation does not establish migration success rates or comparable total costs. |
| Amazon Q Developer | An IDE-based transformation workflow that analyzes an application, creates a plan, groups changes into buildable units, tracks progress, updates C# where needed, and proposes a diff for review. Its documented .NET transformation targets cross-platform .NET and Linux compatibility, with a readiness report identifying unresolved Linux changes. AWS’s transformation overview. | Whether Linux compatibility or AWS-hosted modernization is a specific target, and whether the IDE workflow supports the team’s review process. | The cited overview focuses on Windows-to-Linux porting rather than a full comparable matrix of project types or independent outcomes. Check current transformation job quotas and prerequisites. |
| AWS Prescriptive Guidance and migration tools | Guidance for choosing among rehosting, Windows or Linux containers, microservices and serverless. It also describes tools for scanning .NET code and reporting portfolio roadmaps, and for finding incompatible APIs or packages and possible replacements. Modernization guidance and Microsoft workload migration guidance. | Which hosting and architecture destination fits each application, and how to sequence work across a portfolio. | This is strategy guidance and a set of AWS tools and services, not a directly equivalent IDE-agent comparison. Confirm current availability and product names. |
Decide what “migration” means for each application
Before comparing automation, define the target. “Move off .NET Framework,” “run on Linux,” and “modernize the architecture” are separate goals; combining them into one mandate can turn a runtime upgrade into a larger, riskier redesign.

This is not the same destination as modern .NET. See Microsoft’s scenario documentation.
- Move to modern .NET while retaining Windows: assess the application and its dependencies against the target runtime, without assuming that a Linux move or architecture redesign is also required. Microsoft documents .NET Framework-to-.NET 8-or-later scenarios in its upgrade overview.
- Make Linux a requirement: identify Windows-specific APIs, packages, native components and hosting assumptions early. Amazon Q’s documented transformation explicitly targets Linux compatibility; AWS guidance also treats Windows dependency resolution as a factor in choosing a migration approach. Amazon Q transformation details; AWS modernization guidance.
- Change hosting or architecture: determine whether rehosting, containers, microservices or serverless is justified by the application’s constraints and the team’s capacity. A code agent does not make that decision for you. AWS’s strategy guidance.
Compare the tools at the application level
A portfolio average can conceal the applications most likely to drive effort. Score each application or closely related family against these criteria before selecting a workflow:
- Application shape and language: record whether it is ASP.NET or Web Forms, desktop UI, a service, a library, a console app or a test project, and whether it uses C# or Visual Basic. Microsoft’s documentation covers multiple project types, but says scenario support varies. Microsoft’s scenarios and skills.
- Runtime and operating-system target: distinguish Framework 4.8.1 maintenance from a modern .NET upgrade, and Windows hosting from Linux portability.
- Dependency and compatibility risk: list NuGet packages, APIs, native components and other Windows-specific assumptions. Identify which have supported replacements and which need manual work.
- Review and validation needs: evaluate whether the workflow provides usable assessment, planning, task breakdown, progress visibility, proposed changes, validation and reporting. Confirm that reviewers can inspect changes before accepting them.
- Architecture ambition and capacity: a limited-code-change rehost has a different scope from Linux refactoring, microservices or serverless. Plan the latter only where the expected outcome warrants the dependency work and redesign effort. AWS migration guidance.
- Operational and commercial fit: check current licensing, usage quotas, IDE and repository prerequisites, environment requirements, data handling and cloud operating costs directly with the vendors. The cited material does not establish a comparable price or success-rate benchmark.
Choose a modernization strategy before estimating the work
AWS guidance distinguishes several destination strategies. They are alternatives to assess against application constraints, not a ladder every application should climb.
| Strategy | What to weigh |
|---|---|
| Rehosting | Consider when preserving the existing application with limited code changes is the priority. Check whether its Windows dependencies and target hosting environment make this practical. |
| Containerization | Assess Windows and Linux container options against the application’s compatibility needs and the team’s operating model. |
| Refactoring into microservices | Consider when there is a reason to change the application’s structure and the team has the capacity to address dependencies and redesign. |
| Serverless | Evaluate as an architecture destination where the application’s requirements and redesign capacity support it; it is not an automatic consequence of moving runtimes. |
AWS’s .NET modernization guidance discusses these strategy choices and the role of Windows dependencies and refactoring resources in selecting among them.
Run a pilot that tests the risky parts
- Inventory the portfolio. Capture target frameworks, language, project types, hosting, packages, native components, configuration and business criticality. Microsoft’s assessment material emphasizes code, configuration and dependencies; AWS guidance highlights application constraints that shape strategy. Microsoft upgrade overview; AWS modernization guidance.
- Write down the target for each application. Specify whether it is staying on full Framework, moving to modern .NET, changing operating system, or changing hosting and architecture. Treat the documented .NET Framework 4.8.1 route as distinct from a move to .NET 8 or later. Microsoft’s scenario documentation.
- Choose the hosting and operating-system destination. If Linux is mandatory, investigate Windows-only dependencies before committing to the schedule; Amazon Q’s documented transformation is aimed at that porting goal. Amazon Q transformation overview.
- Select a representative, bounded pilot. Include enough of the real application to expose its difficult packages, integrations and behavior. Run the chosen workflow on a branch, examine its plan and proposed changes, then build, test and exercise application-specific integrations. Microsoft documents staged, branch-based artifacts, while Amazon Q describes a proposed diff that users can verify before accepting. Microsoft workflow; Amazon Q workflow.
- Record what automation did not settle. Track blocked APIs, manual fixes, replacement decisions, build and test failures, and untested behavior. Use this evidence to estimate similar applications, not to assume every portfolio member will take the same effort.
- Price and approve based on current evidence. Combine your pilot findings with current vendor quotes and operational cost estimates. The cited sources do not provide a comparable vendor price or independent migration success-rate benchmark.
What the available evidence can—and cannot—tell you
The cited materials document product workflows and AWS strategy options; they do not report an independent head-to-head migration benchmark. They therefore cannot establish a universal winner, a defensible success-rate ranking, or a comparable total cost. Product names, supported targets and project types, quotas and subscription requirements can change, so verify current details with the relevant vendor before committing to a portfolio plan.
