Hi,
I have a project of migration for two Aruba controllers (Master and Standby setup) from one location to another, this migration will require to change the IP addresses and the Hostnames of the two controllers.
The current setup is having a vrrp on vlan 1 which at the same time represents the controller IP on both controllers. I would like to know what could be the effect of changing the controllers IP on other configuration and how the routing will be done, knowing that there are two subnets as follows:
1- Vlan 1 for controller IP and lms/bck lms IP in the AP-group.
2- vlan 18 which is the default gateway for the traffic.
3- There are two connections between each controller and the core SW
Also, I want to know how the current AP will get the new IP of the master controller after the changes, we are using DNS entry for aruba-master for the current master discovery process and the APs get their IP using a DHCP server. APs have different locations and not in one network.
Appreciate it if one can help me in this regard.
