IBM HTTP Server 7.0 SSL Cert

Hi all, I am wondering if anyone can assist me.  I have been struggling with this for a while now.  We have a UNIX web server (running HTTP Server 7.) and a UNIX application server (running WAS 7.0).  The HTTP Server SSL cert is set to expire and we need to renew it.  I understand that process with ikeyman.sh as it pertains to the Web Server.  My question is how do I know if I need to do anything from a WAS perspective.  It appears that there are SSL certificates in WAS but I am unsure what to do if anything.  Any help is appreciated.
