After upgrading UIM/UMP, received 'The sla_engine probe must be at least version 3.53.' when open slm and slareports portlet even though sla_engine probe is running properly in primary hub.
Drop browser cache and restart UMP robot does not resolve this issue.
Primary hub robot was accidentally changed to use lowercase letters.
Change primary hub to use its original name before upgrade and validate probes and restart primary hub.
Modify probe address in <ump_common> of wasp.cfg to use exact probe address (case sensitive) as seen in IM.
