Upgrade fails on ADE.
This appears to be an issue with Java install as the first part of the upgrade.
Cancel the upgrade
launch Infrastructure Manager
Make sure you have Java_jre 2.02 or later in the archive. ( updated 9 July 2020 )
Stay logged into IM.
Start the upgrade again.
Watch ADE to turn red and the state change to error.
When this happens, from IM, go to the archive and deploy java_jre 2.02 or later to the primary UIM while the upgrade appears to be waiting on ADE.
When it finishes installing, stop the ADE probe on the primary from Infrastructure Manager, then active ADE probe. It should get a port and PID and turn green.
If you did this fast enough, the upgrade should now continue past ADE and you should see the percent completed increasing.
Note: this problem can happen even if java_jre 2.02 is already deployed to the primary hub.
