Hoping to catch Barry's eye here, but welcome help from anyone!

I consider this a pretty basic question that I can't seem to find definitive guidance on now that we've completed the transition from v3 to v4.

I have a v3 initial certification from late 2012 that would like to pursue recertification, but did not register before the 10/31/16 deadline to keep it in v3.

Assuming credit tracking has gone according to plan, can this project theoretically pursue a recertification under v4? Or is there a ruling out there that says the project would need to pursue an initial certification under v4?

Thanks in advance!!
