I moved my secondary domain and mta to the resource in the cluster - all seems to work well, fails over, etc. However......

When I go to console one, i see on the properties of that MTA for that domain, that the tcp address on the network address tab is still that of the old server.

Here is the process I went through:
In c1 I changed the unc path on the properties of the domain to be relocated.
I stopped the associated mta on the old server.
I copied the directory structrure over with xcopy
I installed the agent software
I brought the new mta up on the new server.
commented out references to it in old startup files on old server

So, when I look at MTA properties, can I just simply change the ip address on the network address tab to be that of my cluster resource where this mta and domain are on?
