Changing ESXi host name
Greetings,
We moved a cluster to a datacenter in another city and would like to rename the hosts in the cluster accordingly (the hosts are named by the city they're located in, so I need to change from OLDCITYvmhost01, 02, 03, 04 to NEWCITYvmhost01, 02, 03, 04). I believe the process to be:
Put the host into maintenance mode.
Disconnect the host from the vCenter server.
Connect to the host directly (I am using the stand-alone client).
Go to Configuration > DNS and Routing > Click Properties... then edit the name accordingly.
Click OK.
Go to vCenter web client.
Go to the cluster.
RIght-click cluster and choose Add Host.
Choose renamed host and configure through wizard.
Exit maintenance mode.
Will VMs migrate back to this host, now with a new name? I suspect they will in that the host is part of the cluster and the cluster is configured for HA and DRS. However, I wasn't sure if the VMs that were migrated off of the renamed host when it was put into maintenance mode would have some issue moving back.
Please let me know if there are other locations I need to update the host name, any caveats or errors I may encounter with the cluster, or if there is a reason besides personal preference to use the host's web client to do this.
Much appreciated.

went well but wanted to note some things in case someone else ran across this.
Once in maintenance mode I could not connect to the host I wanted to rename by name or IP from the stand-alone client. Was able to access it through its webpage. The following was my process. DNS was edited a couple of hours before hand, as suggested.
went to host webpage using original name
changed name in networking > tcp/ip stacks > default TCP/IP stack
went to new name of host web page to confirm
also successfully pinged by IP
went to vcenter, right-clicked host (original name) > connection > disconnect
right-click host (original name) > remove from inventory
right-click cluster > add new host > went through wizard and added host (new name) to cluster
exited maintanence mode
VMs started migrating back automatically and with no issue
