# Confirming your repositories to prepare for transformation
<a name="dotnet-confirming-repos"></a>

After [Creating a source code repository connector](dotnet-creating-repo-connector.md), confirm your repositories as the first step of preparing for transformation. You can: 
+ Review and change [Default Settings](#default-settings) that affect the plan contents.
+ Review discovered repositories and select which ones to assess for transformation.
+ Review the [ repository assessment report](https://docs.aws.amazon.com/transform/latest/userguide/dotnet-confirming-repos.html#review-repository-summary) and chat with AWS Transform about its contents.
+ [Use the plan generated by AWS Transform](dotnet-web-app.md#use-generated-plan).
+ [Customize the transformation plan](dotnet-web-app.md#customize-plan) using the web app or by downloading a JSON file, modifying it, and uploading it to AWS Transform.

## Default Settings

In the **Job details** section of the **Collaboration** tab, you can set the following: 

On the Tasks tab, in the Prepare for transformation - Confirm the repositories to transform step, you can set the following:
+ Set the target branch name where the transformed code is written to your repository.
+ Set the target .NET version:
  + **.NET 8**: transform all projects to .NET 8
  + **.NET 10**: transform all projects to .NET 10
+ You can update the default Job Settings, or leave them as-is. These include:
  + **Exclude .NET Standard projects from the transformation plan** This setting is selected by default. When selected, AWS Transform excludes any .NET Standard projects from the transformation plan. If you deselect this setting, .NET Standard projects will be transformed, which will make them no longer compatible with the .NET Framework.
  + **Check the NuGet sources and get .NET compatible package versions** Allow AWS Transform to search for and get .NET compatible package versions for the code that you would like to transform.
