Migrate to Classic Report Designer application

To migrate an ASP.NET Core Report Designer application from Syncfusion^® Essential Studio to the classic Bold Reports^® Report Designer, replace the old scripts, styles, assemblies, packages, tag helpers and control tags with the Bold Reports^® ones. Bold Reports^® introduces new client-side and server-side assemblies to resolve the compatibility problem between Essential Studio Report Designer versions, with changes in both the Web API service and the client-side scripts.

Use these steps to migrate from Syncfusion^® Essential Studio release to Bold Reports^® version lesser than v5.2.xx

The following sections provide step-by-step instructions for migrating the Report Designer from Syncfusion^® Essential Studio release version to Bold Reports^® version of ASP.NET Core Report Designer application.
