Imam,
I think you will have to do something like this:
Copy over the node definition to the new MN
Change BMC IP and Host IPs in the node definition on the new MN
Remove MAC from the node definition on the new MN
makedns -d, makedhcp -d, makehosts -d on the old MN
Stop DHCP server on the old MN
makehosts, makedns on the new MN
bmcdiscover on the new MN
rsetboot <BMC> net
rpower <BMC> on
After that, MAC address in the node definition should be set on the new MN.

hi Mark,
let me explain a bit more. Sorry for not being detailed earlier in my
response.
the node is part of a ROCKS cluster, it is physically( router/switch setup
related) separated from xcat setup/cluster
(here is its config)

I need to bring the node from 10.1.129.x to some 10.240.58.x address. As
is - the node is not pingable from xcat mgmt node.
the node is a bare metal ( Dell R series ).
Current version of xcat is: 2.16.1

Mark,
No, they are on a different net. Machines are on 10.1.254.x and
existing mgmt server is on 10.240.x.

Subject: [EXTERNAL] [xcat-user] node integration to an existing
xcat system?
Hi,
I have a few nodes running centos 7.7 in a different cluster, and I
would like to bring them up another cluster (running xcat) -
without rebuilding them. Initially, I thought I would just change
IP addresses and copy the xcat mgmt. node root SSH key over, but i
figured that might not be the right way to do it, as xcat would
discover the nodes on boot-up and attempt to build them.
what is the best method to bring on a node and add to xcat
environment without rebuilding it?
