If I need to upgrade to the latest version of iRedmail, how do I get the code to go from 1.0 to current Pro version? I do have the .tar to upgrade from 1.1 to 1.2, but not 1.0 to 1.1.

If disabling TLSv1 causes issue for your clients, you have to either upgrade your mail client application, or enable TLSv1 again.

You don't need to download iRedMail installer for upgrade. Please read this tutorial:

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
