Secondary Ledger: Different Calendar: How do you Initialize Balances using Consolidation Workbench?

I created a Secondary Ledger using a different calendar than the Primary Ledger, and am now trying to find information on how to use the Consolidation Workbench to copy period balances from the primary to the secondary ledger.  I have search MOS and all document hits are still not providing clear instruction on how to do this step.  This is a pre-requisite to running the SLA Secondary/ALC Ledger Historic Upgrade.  Is there a white paper or any other information that may assist me in doing this step?  Thanks in advance!
