NS120 CS IP, SPA/SPB IP change

I have NS120 running on proxy_arp on NAS code version 6.0.70.  Due to network segment changes, I need to change the control station IP, SPA/SPB IP.

I work out the steps as per following:

1. Login to Unisphere and update control station management IP/Netmask/default gateway.

2. stop the proxy_arp to revert SPA/SPB back to default.

/nas/sbin/clarion_mgmt. -info

/nas/sbin/clarion_mgmt. -stop

3. Update SPA/SPB IP

/nas/sbin/clarion_mgmt. -start -spa_ip -spb_ip -use_proxy_arp

/nas/sbin/clarion_mgmt. -info

Since the box is also having replicator V2.   I was wondering can I run nas_cel command to update remote celerra IP if not can I perform nas_cel delete and create again.
