I’m waiting for
mido getting stable upgrade to Android Pie/9, but I don’t know when will it come.
Thus, I want to know if to upgrade it, will be mandatory to reinstall the system from fresh, as a totally new image, or if when getting to stable it will be possible to upgrade the system maintaining all data.
In the first case, I will upgrade to testing, not waiting. In the second case, I’ll wait to not lose all my configurations and data.
