Hello,
I am trying to upgrade reporting services for my project from SSRS 2005 to SSRS 2008 R2. I have already taken backup of ReportServer and ReportServerTempDB databases and the encryption keys in Reporting Services Configuration Manager.
The database is also restored successfully in SQL Server 2008 R2. Since reporting services was not installed in SQL Server 2008 R2, I have installed it separately and noticed that "Install but do not configure report server" was the only option available during the installation process.
After this, when I open Reporting Services Configuration Manager to change the report server DB, and select the restored ReportServer DB, the report mode is showing as "unknown" instead of "Native". Due to this, I am unable to restore SSRS.
It would be great if someone can guide me on what is missing and how it can be corrected.
Thanks,
