I would like to tell you about my experience from upgrading from TrueSight Version 11.3.03 to 11.3.04. Maybe you will see some things that you were not aware of and can help you.
And if BMC is reading this, they can maybe fix one or the other issue :-)
On our site TSPS is based on Windows, all TSIM's on Linux.
On the Test Server the database was corrupted after an additional reboot. This could be fixed with https://docs.bmc.com/docs/TSOperations/11304/truesight-presentation-server-does-not-start-due-to-postgresql-db-unavailability-954648736.html
No problem on second TSPS
Also there was an error in the installation log because of the certificates. BMC found out that this is related because the certificate name has been renamed during the time.
But it works correctly.
Earlier the .load Files have been changed during the migration. Customized entries have been removed and also the order of the entries have changed.
In the meantime this works fine, except for the data .load. BMC did not fix it, even there was a Defect created since 11.3.03
Our customized entries have been removed. Funny (really?) thing is: the version number in the header has been changed to 11.3.04
If you should have any git related Files/Directories (like for example directory .git or File .gitignore) within the copied cell directory, delete it or you will have an issue. To be honest, we had this problem within version 11.3.03, I did not test this now with 11.3.04
Same issues like on TSPS because of renamed certificate
That's bad: our certificates Files .cer and .key have been deleted and the corresponding entries in the File /app/sim/tsim/pw/apache/conf/extra/httpd-ssl.conf have been changed to server.crt and server.key. Should not be.
Within this File our settings have been changed during the upgrade from false to true
# MSP-related flags
# Flag to show realm-entry-page for the MSP deployments
Our own settings have been removed during upgrade
Our settings <Connector port="8088" protocol="HTTP/1.1" have been changed to Port 8080
Within the File /app/sim/tsim/pw/server/bin/pserver our customized settings for the CMDB Extensions 11.3.03 have been removed (entries for the jar Files that have been deleted below) and the value "ARGS="-Xms256M -Xmx800M $PS_JVM_ARGS -DHomeLocation=$IM_HOME -cp $PS_CP" has replaced our own Memory settings
And the Files /app/sim/tsim/pw/cmdb/lib/arapi91_build007.jar and arpluginsvr91_build007.jar have been deleted
The new HealthCheckTool proposes several new settings that were so far not in the configuration files. From my point of view it would make sense to set those values directly during the upgrade
That was really good. We had in the past long support cases related to ticketing problems. That works now perfectly, except one small thing (as example for a 3 Cluster Service Modell, if 2 CI's are again ok, all upper CI's UAR's should be closed also. That we could fix with a small change in the outage.mrl
The cronjob entries like hourlyjobs, dailyjobs and so on have been added again, so the entries are twice there. This problem is already since some versions
Hope it gives you some hints.
And we will see soon what's missing if there is no more a Operator Console for TSIM
