I updated UIM to patch 20.3.2 and the installation completed successfully. However, when I tried to open dashboard all the dashboards open with missing icons / custom images and backgrounds.
Release : 20.3
Component : UNIFIED INFRASTRUCTURE MGMT
The hot fix (ump_dashboard) version - 20.32hf2 resolved this issue.
