Finally I’ve found the solution to fix up all the redirectors.
I have to see the references for each moved objects (yes it can be very long).
For each reference, open the asset. Use the browse asset icon. Then clear the asset using the yellow arrow and reassign the asset using the back arrow to use the select asset in content browser.
Validate and Save.
After that check again the references for the object. And if no more link to the redirectory object, Fix up the redirector.
