So you wanna change FQDN or IP of your vCenter? Here is a couple things to consider:
BEFORE CHANGE:
- If you run vCenter in HA mode, you need to disable it
- Must unregister solutions: SRM, vROps, vRNi etc
AFTER CHANGE:
- Regenerate and replace vCenter Server certificates
- Configure vCenter Server High Availability
- Add vCenter Server with an updated host name to Active Directory (AD) if it was configured with AD before the PNID change.
- If you run HA mode for vCenter you need to configure it again with new PNID
NOTE: After the PNID change, the vCenter Server certificates are reset to VMware CA generated certificates.
If you consuider all of it and ready to make a change, please refer to this post:
vSphere 7 – How to change the FQDN and IP (PNID) Address of vCenter Server Appliance
Good luck!
