dotnet migrate - Migrates a Preview 2 .NET Core project to a .NET Core SDK-style project.


dotnet migrate will be removed from the .NET Core 3.0 SDK in the next preview release.


dotnet migrate [<SOLUTION_FILE|PROJECT_DIR>] [--format-report-file-json] [-r|--report-file] [-s|--skip-project-references] [--skip-backup] [-t|--template-file] [-v|--sdk-package-version] [-x|--xproj-file]
dotnet migrate [-h|--help]


The dotnet migrate command migrates a valid Preview 2 project.json-based project to a valid .NET Core SDK-style csproj project.

By default, the command migrates the root project and any project references that the root project contains. This behavior is disabled using the --skip-project-references option at runtime.

Migration can be performed on the following assets:

  • A single project by specifying the project.json file to migrate.
  • All of the directories specified in the global.json file by passing in a path to the global.json file.
  • A solution.sln file, where it migrates the projects referenced in the solution.
  • On all subdirectories of the given directory recursively.

The dotnet migrate command keeps the migrated project.json file inside a backup directory, which it creates if the directory doesn't exist. This behavior is overridden using the --skip-backup option.

By default, the migration operation outputs the state of the migration process to standard output (STDOUT). If you use the --report-file <REPORT_FILE> option, the output is saved to the file specify.

The dotnet migrate command only supports valid Preview 2 project.json-based projects. This means that you cannot use it to migrate DNX or Preview 1 project.json-based projects directly to MSBuild/csproj projects. You first need to manually migrate the project to a Preview 2 project.json-based project and then use the dotnet migrate command to migrate the project.



The path to one of the following:

  • a project.json file to migrate.
  • a global.json file: the folders specified in global.json are migrated.
  • a solution.sln file: the projects referenced in the solution are migrated.
  • a directory to migrate: recursively searches for project.json files to migrate inside the specified directory.

Defaults to current directory if nothing is specified.


--format-report-file-json <REPORT_FILE>

Output migration report file as JSON rather than user messages.


Prints out a short help for the command.

-r|--report-file <REPORT_FILE>

Output migration report to a file in addition to the console.

-s|--skip-project-references [Debug|Release]

Skip migrating project references. By default, project references are migrated recursively.


Skip moving project.json, global.json, and *.xproj to a backup directory after successful migration.

-t|--template-file <TEMPLATE_FILE>

Template csproj file to use for migration. By default, the same template as the one dropped by dotnet new console is used.

-v|--sdk-package-version <VERSION>

The version of the sdk package that's referenced in the migrated app. The default is the version of the SDK in dotnet new.

-x|--xproj-file <FILE>

The path to the xproj file to use. Required when there is more than one xproj in a project directory.


Migrate a project in the current directory and all of its project-to-project dependencies:

dotnet migrate

Migrate all projects that global.json file includes:

dotnet migrate path/to/global.json

Migrate only the current project and no project-to-project (P2P) dependencies. Also, use a specific SDK version:

dotnet migrate -s -v 1.0.0-preview4
