Hey there,
The number on the Aadhar card remains the same even after the update, so you can use your old Aadhar card for now. It won't cause any problem. The information you will provide will be verified through the UIDAI online. If the Aadhar has been updated, it will be shown online, but to get it physically, it can take time.
Hope it helps!!!
