Using Epicor 10.2.500.x, SQL Server 2017. I was wondering if anyone has upgraded SSRS along the way with the different point release versions over time and had any issues? Like moving for example from 14.0.600.689 to 14.0.600.1572?
Those are usually security patches. I personally have not seen or heard of any issues if you patch SQL. If it was an issue, we would not be able to ensure security, right? 
I believe the SSRS upgrades do a bit more than just security fixes, although those are part of each upgrade.
