The following steps explain how to migrate from ActiveReports 10 to ActiveReports 12. The assembly version of DLLs included in ActiveReports 10 is 10.xxx.

1. From the Visual Studio Tools menu, select Convert to ActiveReports 12.
   • If the assembly version of reference files does not automatically change to ActiveReport 12 after running the converter, you need to manually update the reference files. For more details, see Reference Migration.
   • If the license information is not displayed correctly after running the converter, you need to manually update the license information. For more details, see License Migration.
2. If you are using the WebViewer control, see WebViewer Migration.
3. Check the Compatibility Guidelines.
4. From the Build menu, select Rebuild Solution to rebuild the entire solution.
   
   Note: Between versions 1 and 12, we have updated several class names. This may cause syntax errors on migration. To resolve these errors, see the Breaking Changes topic.
