Upgrade process for fontawesome from 4 to 5
<p>We contributed to font-awesome 5 (yea), and we are looking from moving from our existing icons (Symbol set) to font-awesome.   Will the naming of icons and usage of font-awesome 5 be backwards compatible with font-awesome 4.7?</p>

<p><code>IE: Should we go to 4.7 now, and have very easy upgrade to 5.0?
OR should we hold off until font-awesome 5 comes out?</code></p>
