I'm looking a way to pass an issue to developers team from support team in a private manner. An reporter creates issue and a communication starts between those two roles. Once a case is acknowledged it should be passed to developer role. The method I know is to assign issue to developer role, but in this case updates support and developer will be shown to reporter, which is not necessary. I was trying to use "copy" function, but copied case has only original issue without history.

Any advice how to achieve my goal: pass case to developer role and keep communication private communication without reporter?
