One of my team members upgraded the SSRS and SQL servers from 2014 to 2016. Now, rather than doing an upgrade i.e. use existing databases - they uninstalled 2014 and did a fresh install of 2016 for SQL and SSRS. Due to this our reporting server broke. For the DB part - we attached the existing databases so that part was sorted. For SSRS - we detached the new ReportServer and ReportServerTempDB and attached the existing ReportServer and ReportServerTempDB hoping that it would solve the problem partially at least. After doing that we get an error - "The feature: "Scale-out deployment" is not supported in this edition of Reporting Services" whenever we open the Report URL. Can someone please help us? We are blocking some important production reports.
