We're trying to make SFTP work on 7.1 as a client. Few questions: 1. Is it best practice to setup different keys for each host that we'll be sending files to? Any issues with using just 1 set of keys? 2. Do we need to regenerate the keys when we switch to a DR box or to a new system with a different IP? 3. Can 1 dedicated profile be used to send to different hosts or we need to setup 1 for each hosts? Can 1 profile have different public and private keys? Thank you in advance.
