We have 2 nodes in an AlwaysOn group. SQL2014 Enterprise.
We need to change the IP addresses of the nodes, the cluster, and the listener.
They will still remain in the same domain.
The subnet mask shall remain the same.
All will the be the same except the IP Addresses and the default gateway.
What are the steps to accomplish this?
Thanks.

To change the IP address of the cluster nodes themselves, it would be best to evict in each node in turn, change the IP, then add it back

Thanks. Before evicting a node, should SQL be shutdown? Or the AlwaysOn Group be shutdown? Thanks.

Are you using FCIs or just standalone instances in the AGs?

Standalone instance.

The availability group is setup as a role under the cluster.

Windows is setup as clustered, not SQL.

Thanks.

in that case as i said above

Remove the secondary database(s)
Remove the replica from the Availability Group(s)
evict the node from the cluster
Change the nodes IP address
re introduce to the cluster
re apply the Availability Group config onto the sql instance

Our VM servers are in azure cloud and migrating to AWS cloud.

we have 3 nodes in always on availability (1- primary, 1 - secondary, 1 - DR replicas ) for voting purpose using fileshare witness in cluster. SQL Server Version 2012.

After VM's migrating to AWS cloud, IP address will change so how to sort out the issues from Windows cluster and Alwayson Listener.

Thanks

I would say it's likely easier to deploy a new system in AWS and then migrate the database(s) to the new system, is this not an option for you?
