Upgrade to 9.02 from 8.51 fails with an error configuring data_engine probe, at 38%.
Release : 8.51, 9.0.2
Component : UNIFIED INFRASTRUCTURE MGMT
MS SQL 2016
We took the following steps to resolve the problem.
Updated versions of all probes on the primary hub to their respective 9.0.2 version n by using "Update version" in the IM console.
Restarted UIM on the primary. The automated_deployment_engine was crashing and restarting (this was the same probe that the upgrade was failing on).
We updated to 9.0.2 version, still crashing.
Deployed automated_deployment_engine 9.20 and now the process was staying up.
We re-ran the 9.0.2 upgrade and we got past the upgrade error and the upgrade to 9.0.2 completed successfully.
