If you complete an upgrade, the upgrader installer will try and preserve existing settings.

But please make sure you have these settings documented, in case you need to reapply them after the upgrade.

Not all the settings will be preserved.

Preserving the ESX/ESXi Host Configuration
During the upgrade, most of the ESX/ESXi host configuration is retained. However, not all of the host settings
are preserved. The following list highlights key configuration settings that are not carried forward during
an upgrade:
•      The service console port group
•      Local users and groups on the ESX/ESXi host
•      NIS settings
•      Rulesets and custom firewall rules
•      Any data in custom disk partitions
•      Any custom or third-party scripts/agents running in the ESX service console
•      SSH configurations for ESX hosts (SSH settings are kept for ESXi hosts)

For a more comprehensive list of host settings that are not carried over during the upgrade, refer to the
vSphere 5.0 Upgrade Guide

check advanced settings, in ESXi with vSphere Client, to check Syslog Server IP Address is correct.

Much easier to troubleshoot via the vsphere client for this in your case.
