We had a DC migration on Aug 15th 2021 in which our core CA-UIM servers IP got updated. After upgradation we have updated the new IP's in all the required Configuration files. While we are working on something else yesterday, we identified that in one the regional hub log file we could see old primary and failover IP's are reflecting.
150.xxx.x.xxx is old primary Hub
150.xxx.xxx.xxx is old failover Hub
Release : 20.3
Component : UIM - HUB
