RE IP Vcenter

Pros and cons when need to Re IP vcenter with out breaking the certificate. I need to Re IP and change the VLAN. Game plan that is since the certificate is by FQDN and not IP, I was just going to change the IP address of vcenter, change VLAN and update DNS. I don't think this will cause vcenter to break or any issue but would like your opinion.

yes, the certificate is based on the FQDN of the server - the IP address is reasonably irrelevant

however, changing the IP of the vCenter server may cause a problem with any managed hosts - but, as long as everything is using names rather than IP addresses, and you update your DNS, you shouldn't have any big issues - temporary loss of communication until the DNS record is updated on all hosts.

to avoid that - I would generally change the TTL (time to Live) on the DNS record for the vCenter server down to a second or two while you update everything - that forces any machine trying to find it to request the new IP address much faster.

if you are using FQDNs through your organisation, then there will be no issues.
