With respect to exporting the data out of Pro/Intralink, your company needs to decide what data is of value to export. Questions like are they only going to export data that was "released" and/or some other "controlled" life cycle state, does the company have any contractual obligation to keep certain data, etc. need to be answered first before deciding on how best to export the data.
AutoDESK does offer an add-in for Creo to store data in Vault Professional. You could always pay for someone to come in and migrate the data directly from one system into the other.
When I've done an export in the past, only the latest version was required without regard to the life cycle state. Drawing PDF's were the managed data in PLM, not the associated CAD files, so we could always order parts via drawing. I did the export manually after having the search results limitations increased to ensure capturing all the results. Data was exported per product & library. Search for all drawings in the one product, add to WS with NO dependents, search for all assemblies, add to WS with NO dependents, search for all parts, add to WS with NO dependents. For family table items, add all instances. If the family tables are "clean", you won't have any conflicts. If not, you'll need to deal with the conflicts individually. You can search for other file types that are of importance as needed (symbols, formats, tables, etc.). In the WS, create a table display that has useful columns displayed. I'd suggest creating several. Export the table list(s) to a variety of formats (.csv, .html, etc.) to give yourself a record of what data was exported. Export the data from the WS into a folder with the same name as the product/library. You can put a copy of the exported table displays in the folder as well. Repeat for all products and libraries. You should now have a copy of every .drw, .asm, .prt, etc. file on your HD with a listing showing what was exported.
