My company is still running Snow Leopard and we're thinking of upgrading to Mountain Lion soon. We are developing iOs and MacOsX applications and have a small break between the old projects and the new projects. What this means is, that we can start over with the new applications on the new version. But what happens to the old versions? They don't have ARC, Storyboards etc... I know you can switch off ARC but we want to make sure that we will still be able to commit updates to our old projects and we can't efford to put lots of time and effort in the conversion process.
I spent some time reading the user comments below the xCode update on the AppStore and read that the new Version deleted old projects. Of course we have a backup but this makes me uncertain if it's the right step.
Does anybody have experience how this works in a non personal environment? At home I'm running Mountain Lion and xCode converted small projects by itself. I'm just not sure about large scale projects...
