Changing Cluster XL IP address Subnet

[MR1]

Hi,

We have a need to change the subnet of our cluster XL and its members.

I have browsed and ask around and seems there's a couple of way to do it, can anyone share their experience? 

also I assume there will be traffic interruption when we do this? am I correct?

Which one is correct or better?

1. Change through smart-1, install policy. ( will this method change the configuration on the member accordingly?)

2. Change through GAIA or CLI on both members, get interface without topology in smart-1 , push policy?

Thanks

The OS-level config has to be done directly with Gaia.
Second option.
