changing the IP address for a vcenter vm

I have a vCenter VM that need to change IP addesses and VLANs.

Does anyone have a bullet proof method for doing this?

I have googled a lot of items that talk about changing the IP address of a VM, but not of a VM vCenter.

Am I missing something here---is it incredibly easy---or is it so obscure that it may be easier to delete it and recreate it at a location where it should reside?

Thanks.
