The command does not need a database configuration update.Even then the precheck fails with the exception stating there are duplicates. This is because of Multi-Tenancy enabled in vRO
The duplicates in vRO are coming from the fact that they are using a multi-tenanted environment and vro duplicates script is not designed for that.
Remediation Plan
This is how you remediate this problem so that a successful upgrade can be performed
Step:1
Extract the attached archive 00-00-00-00-remove-check-vro-duplicates.zip into the VA you are going to upgrade In the folder: /etc/bootstrap/preupdate.d
Step:2
Execute below command to change permissions
chmod 744 /etc/bootstrap/preupdate.d/00-00-00-00-remove-check-vro-duplicatesThen start the upgrade either through vRLCM or through VAMI.
This should help in progressing upgrade further without any failures.
What is this additional script doing?
This script 00-00-00-00-remove-check-vro-duplicates deletes 00-00-02-check-vro-duplicates
when triggered
#!/bin/sh
rm -f /etc/bootstrap/preupdate.d/00-00-02-check-vro-duplicatesIdeally /etc/bootstrap/preupdate.d/* contains all the scripts which has to run during preupdate phase of vRA upgrade

They are executed sequentially
All we are trying to do is a workaround for an upgrade not to check vro duplicates while running an upgrade resulting in a failure. Hence we are deleting 00-00-02-check-vro-duplicates by inducing another script which will be executed before anything else is executed. As we named it as 00-00-00-00-remove-check-vro-duplicates
