Changing IPs - ODA X-4

Hi

We have an ODA-X4 configured in a bare metal setup- 2 nodes in a non RAC environment

We are planning to move the ODA to a different location and hence the IP's would change once we plug it into the new location

We have the following 4 sets of IP

1. 2 Public IP's - one for each node

2. 2 virtual IP' - one for each node

3. SCAN - 2 IPS resolving to SCAN NAME in the DNS Server

We are looking for guidance and steps on how to accomplish this
