Forum Post: Changing Fiscal Periods

My client is switching to a 4-4-5 year in FY 2014 going forward.  FY2013 is on a calendar year.  In FY 2013, they want to extend the 12th period out do January 4th, which would be 12/1/13 - 1/4/14.  FY 2014 will then start on 1/5/2014 and end on 1/3/2015.  My question is how can I change the 12th fiscal period in FY 2013?  

Can I follow the steps in the KB to delete the SY40100 and SY40101 for JUST FY2013?  I would then enter the Start Date of 1/1/2013 and end date of 1/4/2014 and reconcile 2014.  OR, do I need to delete the entire contents of the SY40100 and SY40101 and recreate all periods, and reconcile?

Thanks!
