Security Concerns of Migrating from Richfaces to Primefaces

I have a small Richfaces web application hosted on a JBoss EAP 6.4 server. I want to now run the app instead on a JBoss EAP 7.0 server, and modify the app to use Primefaces v6.1 instead of Richfaces.

Can anyone tell me (or make an educated guess) as to what may be some new security concerns or implications for doing so?
