This is more of an OCD problem than functional issue and hopefully there is a way to fix this. I migrated 2 Windows vCenter 6.0 to VCSA 6.7 using ui-installer and migration assistant. However, the end result for 1 of the 2 VCSAs has the hostname "vcenter" as "VCENTER", so the server FQDN is "VCENTER.example.com". Now I went in and corrected the values in the vCenter server configuration to lower case and it's showing up in most places correctly. However, in the tasks/events window, it's still showing up with the mixed case. Is there a way to possibly correct this?
With vCenter 6.x the system name (or the IP address, depending on the installation) will become the vCSA PNID (vCenter Server Appliance Primary Network Identifier), and there's no supported way to change this. The Windows hosts likely had its hostname in upper case letters.
