Can I upgrade my AMS from previous version to latest use old License and SN?

Hi All,

       I have 2 questions:

     1. Can I upgrade my AMS from previous version(5.0.2) to latest(5.0.14) use old License and SN?

     2. If I don't upgrade my AMS to latest version, Can I upgrade  dependent libraries for apache module (mod_hlshttp.so)?

               the reason is that,  I upgrade the libs (libcares.so/libexpat.so) to latest by yum install, but they are conflict to apache mod_hlshttp.so dependent libs..

               SO, Can I delete mod_hlshttp.so dependent libs  directly and use yum's libs?

      I 'm here waitting for your help...
