After upgrading UIM from 9.2 to 20.3 we are not able to find any Alarm console in the OC.
We are using MS SQL 2008 as database.
Release : 20.3
Component : Operator Console
This can be related to an incompatible version of database.
Please upgrade MSSqlServer from 2008 to one of the product supported environment.
UIM compatibility matrix is located here:
