Question Rename all Files in a UNIX Directory from one date format to another date format

Hi Unix Gurus,

I would like to rename several files in a Unix Directory . The filenames can have more than 1 underscore ( _ ) and the last underscore is always followed by a date in the format mmddyyyy. The Extension of the files can be .txt or .pdf or .xls etc and is case insensitive ie .Xls or .XLS is also possible. Now i need to convert such a file to date format which ends with yyyymmdd.

For eg E-SSS_Reporting_for_Small_Groups_10012013.xls needs to be renamed as E-SSS_Reporting_for_Small_Groups_20131001.xls

How can i accomplish this?

Appreciate your Help on this.
