currently I am running Chia on one Ubuntu-Server and it has the Version 1.6.2. How do I update this to like 1.7.0? Uninstall the old one, copy over the ca-files before. Install the new Chia-Version with init -ca?
I need to keep the ca-files because some hjarvesters are having the old-ca-files as well and need to sync.
Just install it, it will overwrite anything that needs to be updated. Just have a backup of your .chia and .chia_keys folder for backup. Copy the two folders when chia is not running.
