Hostnames that have mixed case letters may cause problems when upgrading from QRadar version 7.3.x to 7.4.x

Troubleshooting


Problem

During the running of the QRadar SFS upgrade installer with the -t test option. If the test reports a problem with the domain name not matching between what is in /etc/hostname to what is in the QRadar config files, the upgrade installation will not proceed.
This is due to tighter restrictions for hostnames starting in QRadar version 7.4.x where hostnames have to match according to case in order for QRadar to operate.

Symptom

The following Error is displayed after launching the upgrade:
At least one invalid hostname entry was found in one or more deployment settings.
