This exact version will never quite become the official version. Nolen maintains his own versions, although he also contributes to and uses some of the same work that goes into the official versions. So, yes, if you want to switch to the official version when it comes out, you would have to do a clean install. That said, there is also no guarantee that there will be an official version . Of course, I assume there will be, but Lineage could decide to drop support for the Por1 and Pro1x. We don't know until we know (Lineage never answers questions about future versions or support).
