Is the project on a local drive or a network? Upgrades are best done locally.
If you recreate the folder structure in Rh11 and then import, you can ignore the broken links as you go. Once all is imported, they should have dissappeared.
Given the previous history, it does sound like a dodgy project. Can you open it in Rh10, delete the CPD and reopen it in Rh10 to create a new one, then close it and open in Rh11? Just an idea.
Do zip up their project as it is now so that there is an untainted copy to keep going back to.
