Planning to change the vcenter6.7 vsca domain and ip details to different subnets
So after changing the details . vcenter will have connectivty with the connected hosts earlier or it will go to non responding state..
Note: we have firewall openings to new vcenter ip to esxi (bi dierctional).
Example : Vcenter is in abc.test.com ip : 10.0.0.20 changed to xyz.test.com and ip to 172.16.201.20.
Please suggest the wayforward. or shall i go with fresh vcsa installtion in new domain and adding the hosts to this vcenter by disconnecting from the old vcenter
If you are using vcsa 6.7 embedded, then you can surely change the fqdn and IP of the vcenter.
When you are ready to change it, need to make sure the DNS records are updated and ESXis are able to resolve the same.
You can follow below documents for reference for this process,
