Query in tally

Hi,

   Greetings of the day.

    I am having a query in Tally ERP 9.0. The entries for the year 2008-09, 2009-10, 2010-11 are in one company directory. But i have wrongly made the entries for f.y. 2011-12  of the same company by creating a new company directory. Is there anyway to transfer the data of new directory F.Y.2011-12 to the old directory of the same company??

   If it is, kindly tell me the path how to transfer the same.
