Clarification on Credit Roll Over When Downgrading Plans

Hey Team. I currently have 27809 credits remaining in my account The renewal date is 14th May. I am currently on the 'pro' monthly plan with 70k credits. However, for this month renewal I will probably move to 'explorer' plan with 10K credits due to reduced demand for the month. I wanted to check if my 27809 credit will roll over to the new month even though I have downgraded to a new lower plan for the month? If you can please confirm how the 2x roll over works.
