Change New lease date

[Sami Gren]

Hi, 

I have a section 8-tenant In New Jersey and the lease anniversary date was Nov. 1, I made him sign already my renewal document for Nov 1 In addition to the official section 8 document, 

however when i sent it in to section 8  they have told me that since last year he qualified for a rent increse begining Feb 1 they have changed the date of the aanniversary to Feb 1.

my question is since the original lease in my renewals were dated for Nov 1 and  my lease  probably needs to be  on same date, how should I go about changing my personal lease. 

Do I need to make him sign a full new lease with the new date?
