Hi Prashanthi,
Thanks for using Syncfusion Products.
Could you Please follow the below mentioned steps to resolve the licensing issue.
1)If you are using Syncfusion version after 8.2.x.x ,Remove the license.licx file from your project, Because Syncfusion had removed run-time licensing for all Essential Studio products from the version 8.2.0.x.
2)To upgrade your projects to the latest version.
We have a project migration tool in our latest version(9.3.0.61) which is used to migrate project from one version to another version.
Please find the project Migration tool from the below location:
Start->All programs->Syncfusion->Essential studio 9.3.0.61->Tools->Project Migration-> Syncfusion Project Migration
Or
You can find the utility from the below installed location.
{Installed location}\ Syncfusion\Essential Studio\ {Essential Studio version}\Utilities\ProjectMigration\ProjectMigrationWindows.exe
For ex:
C:\Program Files\Syncfusion\Essential Studio\9.3.0.61\Utilities\ProjectMigration\ProjectMigrationWindows.exe
If you want to manually upgrade project from one version to another version, then please follow the below KB article.
