Verify compatibility with your hardware, operating systems, software applications, and third-party services. Test the new protocol on all platforms your organisation uses. 5. User Acceptance Testing (UAT)
26 Αυγ 2015 · FTP over TLS (FTPS) uses port 990 (TCP/UDP) for control and port 989 (TCP/UDP) for data.
