We're switching our connection to the publishing server from FTP to SFTP (after
having configured the publishing server for that using openSSH). I've figured
out how to change that connection in the Contribute Admin section, but I
haven't pushed the final button yet because I want to know if that will
completely alter the connection information all our staff are currently using
FTP to connect. If it does alter it, will we have to re-issue a new connection
key or will it simply ask them to re-enable their connection on the client end
(enable-->trust the server, etc.)?

Thanks in advance.
