Frank, You should change to AT-TLS
SECURE_MECHANISM ATTLS That will get TLSv1.2 support but just as important will allow you to use newer cipher suites. Many of the older cipher suites supported by the FTP client (or server) internal SSL/TLS function have been the subject of security warnings over the last couple of years. Do you subscribe to IBM's security vulnerability warnings?

This new server we have is (currently) configured to support only TLS v1.2, and nothing earlier. We're trying to get approval to "back down" to TLS v1.0, but I figured I'd ask this anyway.
