Data Migration PDM

I have PDM Workgroup.

The revision scheme was set many years ago with Primary (Numeric) & Secondary (Alpha) established. Now we want to change that for more flexibility.

The new scheme will be Primary (Alpha) & Secondary (Numeric) while using Lifecycle. R&D, Released, and Released R&D.

Essentially all we added was Released R&D, because after all with the price of metal skinny parts cost less.

Now that I have a bazillion models with parts, drawings, and assemblies, how do I migrate all the data over???

I see PDMWEXPORT.exe and PDMWIMPORT.exe but where is the help info? Can I use that while changing the revision scheme??
