I have a cluster with a set of IPs which is working fine
I want to move that host to another network with different IPs
until Vertica 7.1 I could do it.
How can I do it now?
You'll need to contact support. The IP address is stored in the Vertica catalog, but they have a tool which you can use to do it fairly easily.
I did not. I created a new Cluster and used the copy from Vertica to pass the data.
Very bad move to have a special tool unavailable to all users for this. until 7.1 we were able to move the clusters as needed!
