Adding a secondary Ledger to our Primary Ledger

We have a need to create a new seonday ledger with a fiscal calendar from APR-MAR our primary ledger is on a Calendar Year from JAN-DEC. We have transactions from 2008 and would like to be able to convert all the history in our primary ledger to this newly created secondary ledger. I have found a couple of hits that say that the following program was introduced in R12 SLA Secondary/ALC Ledger Historic Upgrade hwoever i do not see this anywhere in our version.
