With FRx not being compatible with Management Reporter, it's time to make plans now so it doesn't become a barrier into upgrading. The Management Reporter release schedule is a rapid release schedule with features being added in a quick succession, so if you haven't looked at it in a while, now is the time to look into it.
I've compiled a few links to information to help you get started on learning about Management Reporter and planning to move.
