I need to upgrade and migrate from SSRS 2012 to 2017. Database backup/restore seems work I can see that the objects in old database and database created new by SSRS 2017 Configuration might be different , because when I went through in place upgrade on 2012 server there was a warning : migrate your reports first/ SSRS 2012 will be uninstalled...)
But when I use powershell migration scripts and rs.exe I can't migrate Users/Security Setting nor DataSourse passwords
can someone confirm that backup/restore is a safe way Upgrading from SSRS 2012 to SSRS 2017?
