PeopleSoft FN 9.2 calendar change from 1/1-12/31 to 12/1-11/30

Client is on PeopleSoft FN 9.2 and currently uses a calendar year of Jan 1 - Dec 31. They would like to change it to Dec 1 – Nov 30.

They have the following modules in place:

· Billing

· Receivables

· Payables

· GL

· Assets

· Contracts

· Projects

· Expenses

· Purchasing

Do you have any suggestions on the proper approach (configuration, sql, etc), timings and things to consider when changing the calendar?

Thanks in advance!
