You guys are great! After a few minutes I had several answers that put me in the light. The consenus was, that I do not have to upgrade or convert these common parts in Commonspace, since WF3 and WF4 will read WF2 files. If a common part does need changing then I would un-lock it, make the change, check it in and re-lock it. I quess I was still in the frame of mind of having to do a conversion, since we just went through the migration of our Intralink data from 3.3 to 3.4. Thanks again for all you help.
