I'm in the process of migrating an assembly created in SW2004 over to 2009. The initial modelling work was done for a project that got put on the back burner, but has now been resurrected. In that time some of the components and sub assemblies have changed and no longer fit in the original assembly. I'd quite like to have the history available within PDM works.

My question is this:

Is there a way to reference out of date revisons of parts and sub assemblies in an assembly?
