## Introduction

{% data variables.product.prodname_copilot %} can help streamline the process of modernizing and upgrading your Java and .NET applications. {% data variables.product.prodname_copilot_short %} will analyze the project, generate a plan, automatically fix issues it encounters when carrying out the plan, and produce a summary.

## Upgrading Java projects

You can upgrade a Git-based Maven or Gradle Java project using {% data variables.product.prodname_copilot %} in {% data variables.product.prodname_vscode %}. You will need:

* Either a **{% data variables.copilot.copilot_pro %}**, **{% data variables.copilot.copilot_pro_plus %}**, **{% data variables.copilot.copilot_for_business %}** or **{% data variables.copilot.copilot_enterprise %}** [subscription plan](/copilot/about-github-copilot/subscription-plans-for-github-copilot).
* The latest version of [{% data variables.product.prodname_vscode %}](https://code.visualstudio.com/).
* For Maven-based projects, access to the public Maven Central repository.
* Installed versions of both the source and target JDKs.

For an overview of the modernization workflow, see [AUTOTITLE](/copilot/tutorials/modernize-java-applications).

## Upgrading .NET projects

You can also upgrade a .NET project using {% data variables.product.prodname_copilot %} in {% data variables.product.prodname_vs %}. You will need:

* Either a **{% data variables.copilot.copilot_pro %}**, **{% data variables.copilot.copilot_pro_plus %}**, **{% data variables.copilot.copilot_for_business %}** or **{% data variables.copilot.copilot_enterprise %}** [subscription plan](/copilot/about-github-copilot/subscription-plans-for-github-copilot).
* The latest release of {% data variables.product.prodname_vs %} Enterprise, Professional or Community 2022.
