 VCF 9.0.1 How to update DNS IPs for VCF 9.0.1 environment. While deploying the VCF, I deployed it with only one Domain Controller which was serving NTP & DNS for the deployment itself. Post deployment, I had to reboot the DC and realised that there is only one DNS and NTP serving the whole stack, so I had to build a redundant DC and join it as secondary DC.  Once I finished with secondary DC, I had to update the secondary IP address on all the components, so make the new IP usable on all components, you have to update it on SDDC Manager and follow these steps. I have used VCF API Explorer in the SDDC Manager's Developer Center. Step 1: Perform a GET request to view the current configuration.
