If you prefer copying the tables wholesale using DBA tools, the tables you need to replicate are the F9000 Task Master, The F9001 Task Relationships, and, assuming you've done your fine cuts, the F9006 Variant Detail tables.
However...
Copying these table from DV to PY should be a one shot deal. I strongly urge you to learn how to use OMW as the change management tool to promote any future revisions to your menus to PY and PD.
A note on the Record Copy in the Content Development Tools: Support for this program ended when Task Explorer was incorporated into OMW with 8.11. It's still available, and it works, but if you have problems with it you are on your own. Get to know and love OMW.
