What worked for me with PCNG was:
1. Upgraded most Products to 2.1 compatible.
2. Uninstall Skin customizations and any other incompatible product like 
3.In Plone 2.0.5 drop in TextIndexNG and PCNG into the Products 
directory and restart Zope.
4.Then copy data.fs to a fresh 2.1 install with all of the new products, 
plus the new plone.
5.Start this new fresh instance and then test migration.
6.Rewrite or test your old skin.

It's possible to skip step 4 and just remove Plone 2.0.5 products and 
put in 2.1.3 but I found it easier to just use a 2nd instance.
*Zope version must be the same on both instances. If you want to try a 
zope upgrade do it after the plone upgrade.
