We have a web front end server with TLS 1.0 enabled for web application in IIS.

This WFE communicates internally with external workflow manager server through fqdn and TLS 1.0

If we enable TLS 1.2 in WFE server, will the communication break between WFE and external workflow manager?

Can we have simultaneous support for TLS 1.0 and TLS 1.2?
