We could see the General tab in data engine probe is in disabled state , and also it is showing a message this is a secondary connection and we could see old server name in primary connection.
While we try to validate the cfg file we identified data_engine_id is "2" in new server (2019) and "1" in old server (2012).
DX UIM 20.4.* / 23.4
Guidance
1. Run the below query and check the data_engine state.
select * from tbn_de_controller
2. Update the old/secondary hub state to 'notprimary' by using where id=1 as per the below query
update tbn_de_controller set state ='notprimary' where id=<id_toupdate>'
Example:
3. Deactivate and Activate the data_engine probe.
Primary should have a data_engine_id of 1 and secondary/HA failover should have a data_engine_id of 2.
