Updgrade from EV 9.0.1 to 9.0.4 Licensing

I will be updating EV and DA both on the same server.  The EV upgrade does not mention anything about licensing and DA has instructions to upload a license file during the update.   Since this is a revision update do I have to worry about licensing with EV and do I just upload the existing license I have for 9.0 into DA again.

Thanks
