I have a SQL 2012 instance called LTT and SSRS 2012 on the same server. The SSRS2012 uses LTT as the Report Server Instance which is fine. On the same machine, I also need SSRS2017. After the installation of SSRS2017 it is using SSRS as its Report Server Instance. But I need it to use LTT (the same as SSRS 2012) how do i change the Report SErver Instance. Using SQL Management Studion I am able to connect to LTT Report Server but unable to connect to SSRS.
