If you want to migrate to 360, then you can do that voluntarily anytime although admittedly the cost should be FOC as part of an Ultimate Oomph bundle.
My only suggestion is to make sure you want to migrate, and am not just doing it because of advertising. It's a permanent migration which can't be reverted, and as things stand, 360 doesn't match TiVo/V6 for all functionality.
It has some improvements for sure, but it also has some shortcomings - so whatever you decide, do so on an informed basis.
