We always ask our customer to provide an updated SDC with the new netlist. You can continue with the warnings about missing nets, but it won't be a very accurate test, because you'll be missing constraints. It's possible you could look at the new netlist and tell what the constraint needs to be changed to, but this can be difficult unless you are very familiar with the design. My opinion is that you need to press for matching constraints.
