Switching from Course 2 for Grade 2/3?

I’ve taught CSF Course 2 for 6 years to Grade 2/3. I have extra activiites to support the lessons & I’m very nervous about switching. Will I be able to continue with Course 2 online even if it’s not supported? We just need to watch the videos in Lessons 1-5 & track student progress. If not, what new course is the closest & most suitable for Grade 2/3; is it Course C? Is it called CS Discoveries unit 2 or is that different? If the courses are shorter now, could we do Course C & D in 8 hours? Is there a video to help me learn how to teach Course C & D please?
