Prepare your solution

To prepare for the upgrade, you must:

• Update the Nuget package references.
• Recompile your solution with the updated Sitecore DLLs and fix any breaking changes.
• Adjust the configuration patches for the new Sitecore version.
• Prepare the artifacts for deployment – containers images, WDP packages – including the modules that you plan to use.

Before you deploy your solution in a production environment, we recommend that you test your customizations on a test system.
