ib to esa wrag contributary 365 day rule??

I think after a medical I am about to be put in esa wrag group from I.b. (been on ib for 5 years) , am I right in thinking that I will get esa benefit for 365 days from date of decision ?, I do not qualify for income related esa.

As I understand it, the 365 days start the day after your IB ends.
