Issue/Introduction

On the migration document. When testing connectivity from current repository to new repository I am being asked for password. Started through doc for creating passwordless ssh. When I enter first command ssh-keygen -N "" -t rsa -f ~/.ssh/id_rsa tells me id_rsa already exist do i want to overwrite?

Just want to make sure this will not affect my current environment by doing the following commands and then copying them to the other nodes.

ssh-keygen -N "" -t rsa -f ~/.ssh/id_rsa

cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys2

chmod 644 ~/.ssh/authorized_keys2


Thanks

Resolution

Vertica copy cluster requires that Linux and Database admin username need to be the same on the Primary cluster and the target cluster. You will need to reinstall Vertica with the same database admin username on the target cluster.
