We would like to upgrade our SQL Server from Standard 2005 to Enterprise/Standard 2012. Unfortunately, we also have a lot of reports based on Reporting Services 2005. If possible we would like avoid upgrading them at this time.
Is it possible to run Reporting Services 2005 of SQL Server 2012? If yes then is there pre-requiste like drivers or dll or any other to connect SSRS 2005 to SQL server 2012?
If we run Reporting Services 2005 of SQL Server 2012 then do we will face performance lag issue due to version difference of SSRS 2005 and SQL server 2012?
