I'm curios if I can convert an existing Next-Gen project with issues and settings into a Classic project? Say, I'm unhappy with the Next-Gen feature set and would like to access the features that are only available to Classic projects, which I'm used to. Obviously, I would make a trade-off and lose the features that are only available on Next-Gen, but ultimately that's a trade-off I might be willing to do in certain circumstances.
If that's not possible, is it possible to export issues that exist in a Next-Gen project, create a Classic project and then import them there?
You probably notice what I would like to achieve, so if there's any other way to get existing issues and some settings, workflows, etc. from Next-Gen to Classic, I would be more comfortable with starting a new project with Next-Gen if I would know I can convert it to a Classic one if I really want to access some features I might end up missing from my experience with Classic.
