Hey there do you use DNS for vCenter and ESX?

My steps would be:

1) vsphere client login to existing center, disconnect all hosts and remove

2) stop vcenter services and change IP

3) start vcenter services

4) change the ESXi IP address from the console x 3

5) vsphere client login to vcenter new ip address, and add 3 hosts.

ensure that all dns or hardcoded host name are changed as well.

When you change the IP address of the vcenter server you may lose connectivity with the esx hosts - checkout this Kb article.
