Move the VM to the other DC and change the IP address.
There's a big caveat here of which you should be aware. If you have installed and configured this vCenter using an IP address rather than a hostname, you will not be able to change the IP address. The reason is described in this KB and has to do with the primary network identifier (PNID) used by vCenter during installation. The PNID is set equal to the value you provide in the "System Name" field during installation. An upgrade of 6.0 to 6.5 inherits this PNID. In general, I'd recommend not changing the IP address of vCenter even if this isn't the case as, more often than not, it causes lots of problems with auth and internal services.
Thank you for your reply. Could you please tell me how can I confirm the current PNID that was used when vCenter was built?
From the appliancesh on vCenter, run
com.vmware.appliance.version1.networking.dns.hostname.get and it will either return an IP or a fully-qualified domain name. If it returns an IP address you're out of luck and will have to redeploy.
Hi the vCenter is currently windows... Whats the command to run to get the above for windows?
Thanks for your help!
