I work on an on-premise network, and we have an Ansible server connected via SSH-Keys to around 400 servers. I've wanted to recreate the Ansible VM, due to the fact that it was poorly made on top of the fact that it is on an unstable, soon to be out of service data-center.
What is the best way to get those 400~ servers to work with the new Ansible server via SSH-Keys?
Any help is highly appreciated.
