EV Licensing getting expired

Hi Team,

I request for the help here. We are using EV 10.0.4 for Exchange. Our EV licensing getting expired in 1 week. I went through different Technote and see a reference for replacing the new license files. Here is my question. What would be the impact when the license gets expired? Does all EV services will get stopped?

Any help on this will be greatly appreciated. Thanks in advance.
