I'm working on a .NET Framework 4.6 solution with several projects, some of which making use of Secure Mail v2 for simple automated IMAP sending and checking tasks. We're thinking of upgrading to the latest version of Secure Email, which I believe is version 6, in part so we can use TLS 1.2.
However, we're curious about how much refactoring might be expected. Of course, I understand this can't be answered in detail without knowing the code base. However, generally speaking, would such a big version upgrade be expected to require a significant code rewrite, or might it largely work as-is?
In general, only very little refactoring is needed even when upgrading even from very old version of Rebex Secure Mail. How old is the version you currently use?
