The Syncfusion ASP.NET Core migration add-in for Visual Studio allows you to migrate an existing Syncfusion ASP.NET Core application from one version of Essential Studio version to another version. This reduces the amount of manual work required when migrating the Syncfusion version.


The Syncfusion ASP.NET Core (Essential JS 2) Web Application Project Migration utility is available from v16.3.0.17.

If this extension not installed, please install the extension by follow the steps from the download and installation help topic. Also, check whether the corresponding Essential Studio version build installed or not. If the Essential Studio version is not same for both the Extension and build, then the Project Migration will not be shown.
