After post upgrading IDM, we see that 1 step is missing during the IDM startup -
Startup Step 28 : Attempting to start NIMSMIntegrationService
This step is missing post upgrading IDM from 14.3 to 14.4
Release : Identity Manager 14.4
FYI
14.4 startup script has been changed. If you don't have ca-nim-sm.war, it won't display during start-up.
Refer to the following link for the NIM service
