Challenger Series Questions

Good morning,

I am currently a coach for a team that has aspirations of reaching the Challenger Series and eventually the LCS in the future. I am trying to get my team to reach the CS by Spring of 2017 and was wondering how exactly we could get into the CS Qualifiers with the new re-introduction of ranked 5s. I know it used to be like the top Challenger teams and such but i was wondering is that still the case? If you could get back to me at your earliest convenience and help shed some light on this or just point me in the right direction of where to look it would be very appreciated. Thank you
